At the absolute beginner level, understanding this word is primarily about recognizing its function in presenting a simple choice between two everyday objects or basic actions. When you are just starting to learn English, you will often encounter situations where you have to pick one thing from a pair. For example, if someone offers you a drink, they might ask if you want tea or coffee. You can use this word to say that one or the other is fine with you. It is a very helpful word because it saves you from having to repeat the names of the objects. Instead of saying 'The red apple is good and the green apple is good', you can simply point and use this word to show that one of the two options is acceptable. At this stage, it is crucial to remember that this word only works when there are exactly two things to choose from. If there are three things, you cannot use it. Teachers often use visual aids, like holding up two different colored pens, to demonstrate how this word singles out one option from a pair. You will also learn to use it with the word 'or' to connect two simple ideas, like 'We can walk or take the bus'. This basic correlative structure is fundamental for expressing alternatives in daily life. Furthermore, beginners are introduced to its use in short, negative agreements. If a friend says 'I do not like Mondays', you can respond by adding this word at the end of your sentence to show that you feel the exact same way. This helps in building basic conversational skills and showing empathy or shared opinions with others. While the grammar rules might seem a bit strict at first, especially the requirement to use a singular noun immediately after it, consistent practice with common pairs of items will quickly make its usage feel natural and intuitive. Mastering this word at the A1 level provides a strong foundation for more complex decision-making sentences later on.
As you progress to the elementary level, your understanding of this word expands beyond simple choices to encompass more detailed everyday scenarios, such as shopping, asking for directions, and making plans with friends. You begin to use it more confidently as a determiner before singular nouns, understanding that it emphasizes the availability or acceptability of one option out of a specific pair. For instance, when looking at two different shirts in a store, you might say that one or the other looks nice, demonstrating your ability to evaluate alternatives. You also become more adept at using the 'either...or' conjunction pair to create compound sentences that present clear, mutually exclusive possibilities. This allows you to articulate more complex thoughts, such as 'You must either finish your dinner or you cannot have dessert'. This structure is essential for setting conditions and outlining consequences in everyday communication. Additionally, the A2 level introduces the phrase 'either of', which is followed by a plural pronoun or a plural noun phrase. This construction is incredibly useful when you want to refer to one individual within a specific, known pair of people or things, like asking 'Do either of you know the answer?'. This shows a developing ability to specify and reference groups accurately. You will also continue to refine your use of the word in negative agreements, ensuring that it is placed correctly at the end of the sentence to mirror a negative statement made by someone else. This conversational tool becomes increasingly important for maintaining smooth and natural dialogues. Furthermore, you might start noticing the slight pronunciation differences between American and British English, although producing both perfectly is not required at this stage. The focus remains on clear communication and grammatical accuracy in familiar contexts. By mastering these varied applications, you significantly enhance your ability to navigate daily interactions and express your preferences and decisions with greater clarity and confidence.
Reaching the intermediate level means you are now capable of utilizing this word with a higher degree of grammatical precision and stylistic awareness. You understand that it is not just a tool for simple choices, but a versatile component that can function as a determiner, pronoun, and conjunction in more complex sentence structures. You are comfortable using it to link longer clauses and phrases, ensuring that the grammatical elements following both parts of the 'either...or' correlative pair are parallel. This attention to parallel structure marks a significant step forward in your writing and speaking abilities, allowing you to construct sentences that are not only grammatically correct but also elegant and easy to follow. For example, you can confidently say, 'The manager will either approve the new budget today or request further revisions tomorrow', maintaining consistency in the verb forms. You also have a solid grasp of the subject-verb agreement rules associated with 'either of'. While you recognize that native speakers might use a plural verb in casual conversation, you know that formal writing traditionally requires a singular verb when the subject is 'either', even if it is followed by a plural noun phrase. This awareness of register and formality is a key characteristic of B1 proficiency. Furthermore, your use of negative agreements becomes more nuanced. You can seamlessly integrate the word into longer, more complex conversations to express shared negative experiences or opinions without hesitation. You are also fully aware of the distinction between this word and its negative counterpart, 'neither', and can switch between them accurately depending on whether you are presenting viable options or rejecting them entirely. At this stage, you are also likely comfortable with both major pronunciations and can understand them without difficulty in various listening contexts, from podcasts to news broadcasts. Your ability to use this word effectively now contributes to your overall fluency and your capacity to engage in more sophisticated discussions about alternatives, plans, and shared perspectives.
At the upper-intermediate level, your command of this word is characterized by a deep understanding of its subtle nuances, its role in cohesive discourse, and its potential for rhetorical emphasis. You are no longer just using it to state simple facts; you are employing it to structure arguments, highlight dilemmas, and create balanced, persuasive communication. In written English, you expertly use the 'either...or' construction to frame complex issues, ensuring strict adherence to parallel structure even when linking lengthy and intricate clauses. This demonstrates a high level of syntactic control and contributes significantly to the clarity and professionalism of your essays and reports. You are also highly sensitive to the register and context in which you use the word. You understand that while 'either of' followed by a plural verb is common and acceptable in informal speech, strict adherence to the singular verb rule is expected in academic or formal professional writing. This ability to adapt your grammar to the appropriate context is a hallmark of B2 proficiency. Furthermore, you can use the word effectively in negative agreements to build rapport and demonstrate active listening in complex social or professional interactions. You understand how its placement at the end of a clause subtly reinforces shared negative sentiments, contributing to the pragmatic flow of conversation. You are also fully capable of distinguishing this word from similar terms like 'both', 'neither', and 'any', even in tricky or ambiguous contexts. You recognize when a situation involves more than two options and automatically switch to 'any' without hesitation. Your listening comprehension is advanced enough that you can easily process rapid speech where the word might be unstressed or pronounced differently depending on the speaker's regional accent. Overall, your use of this word at the B2 level is accurate, appropriate, and sophisticated, reflecting a comprehensive mastery of its grammatical and semantic properties within the broader context of the English language.
Achieving advanced proficiency means that your use of this word is practically indistinguishable from that of an educated native speaker. You possess an intuitive grasp of its syntactic flexibility and its subtle pragmatic implications in a wide variety of highly complex contexts. You employ it effortlessly in sophisticated academic writing, legal documents, and formal debates to articulate precise binary conditions, mutually exclusive hypotheses, or strict alternatives. Your application of parallel structure within 'either...or' correlative constructions is flawless, even when coordinating complex prepositional phrases, dependent clauses, or infinitive phrases. You understand that this balance is not merely a grammatical rule but a crucial rhetorical device that enhances the persuasive power and logical flow of your arguments. In terms of subject-verb agreement, you navigate the nuances of 'either of' with complete confidence, deliberately choosing between singular and plural verbs based on the specific stylistic requirements of the text and the subtle emphasis you wish to convey regarding the individuality versus the plurality of the options. Furthermore, you are highly attuned to the prosodic features associated with the word. You know exactly how to use sentence stress and intonation to highlight the word when you want to emphasize the exclusivity of a choice or the absolute nature of a negative agreement. Your pragmatic competence allows you to use the word to subtly manage conversational turn-taking, express polite disagreement, or establish solidarity through shared negative perspectives in highly nuanced social interactions. You are also aware of less common or slightly archaic usages of the word, such as its occasional appearance at the end of an affirmative sentence in certain dialects to mean 'as well', though you know to avoid this in standard usage. At the C1 level, this word is a fully integrated, highly refined tool in your extensive linguistic repertoire, allowing you to express complex duality and alternatives with absolute precision and stylistic grace.
At the level of mastery, your understanding and application of this word transcend basic grammatical rules and enter the realm of deep linguistic analysis, philosophical nuance, and exceptional rhetorical skill. You recognize the word not just as a determiner or conjunction, but as a fundamental operator of binary logic within the English language. You can effortlessly deconstruct complex syntactic structures where the word is embedded, analyzing its scope and its interaction with other quantifiers and logical operators. In highly specialized fields such as formal logic, computer science, or advanced legal drafting, you utilize the word to define precise, mutually exclusive parameters with zero ambiguity. Your command of stylistic variation is absolute; you can deliberately manipulate the 'either...or' structure to create specific rhythmic effects in creative writing, using it to build tension, highlight profound existential choices, or construct elegant chiasmus. You are acutely aware of the historical evolution of the word and its etymological roots, understanding how its usage has shifted over centuries and how it continues to evolve in contemporary dialects. You can engage in sophisticated sociolinguistic discussions regarding the regional variations in its pronunciation, analyzing how these differences function as markers of social identity or geographical origin. Furthermore, your pragmatic mastery allows you to use the word with extraordinary subtlety in negotiation or diplomacy, employing it to frame ultimatums politely, concede points strategically, or establish complex conditional agreements. You intuitively grasp the psychological weight the word carries when presenting dilemmas, and you use it to guide the listener's or reader's cognitive processing of alternatives. At the C2 level, your relationship with this word is characterized by complete syntactic control, profound semantic understanding, and the ability to wield it as a powerful instrument of precise, nuanced, and highly effective communication in any conceivable context.

either 30秒了解

  • Indicates a choice between exactly two options.
  • Functions as a determiner, pronoun, or conjunction.
  • Used at the end of sentences for negative agreement.
  • Requires a singular noun when used as a determiner.
The word either is a fascinating and highly versatile determiner in the English language that fundamentally revolves around the concept of choice, duality, and binary options. When we utilize this specific term in our daily conversations, we are explicitly indicating a selection between exactly two distinct entities, individuals, possibilities, or outcomes. It is a linguistic tool that allows speakers to present alternatives without necessarily committing to one specific choice immediately, thereby offering flexibility and openness in communication. Understanding the precise meaning of this word is absolutely crucial for learners of English, as it frequently appears in both spoken and written contexts, ranging from casual everyday dialogues to highly formal academic or professional discourse. The essence of the word lies in its ability to single out one item from a pair, emphasizing that one or the other is applicable, acceptable, or relevant, but not both simultaneously in most standard affirmative contexts. To truly grasp the depth of its meaning, one must consider the psychological aspect of decision-making that the word inherently implies. It places the listener or reader in a position where they must evaluate two distinct paths or objects.

You can choose either the red shirt or the blue shirt for the party tonight.

This presentation of alternatives is not just a grammatical structure; it is a reflection of human cognition and our constant need to navigate a world filled with choices. Furthermore, the word can function not only as a determiner but also as a pronoun, a conjunction, and an adverb, each carrying a slightly nuanced variation of the core meaning of duality.
Determiner Usage
Used directly before a singular noun to indicate one of two choices.
When functioning as a determiner, it modifies a noun to clarify that the statement applies to one of the two items mentioned. This is perhaps the most common and straightforward application of the word, easily understood by beginners but retaining enough complexity to be used in sophisticated arguments.

I would be happy with either outcome of the upcoming election.

It is also important to note the negative implications when combined with other words. For instance, when used in negative agreements, it serves to align one's negative stance with someone else's previously stated negative stance.
Negative Agreement
Used at the end of a negative sentence to show agreement with another negative statement.
This specific usage highlights the word's adaptability and its critical role in maintaining conversational flow and social cohesion through shared sentiments.

If you do not want to go to the cinema, I do not want to go either.

The pronunciation of the word also adds an interesting layer to its identity, with two widely accepted variations existing across different English-speaking regions, which we will explore in detail later. Regardless of how it is pronounced, the core semantic value remains entirely unchanged. In summary, this word is an indispensable component of the English lexicon, providing speakers with a precise and efficient means of expressing duality, alternatives, and mutual exclusivity.

We can take either train and still arrive on time.

By mastering its various forms and functions, learners can significantly enhance their ability to articulate complex thoughts and navigate the myriad choices that define human experience.
Conjunction Usage
Used with 'or' to connect two clauses or phrases, presenting them as mutually exclusive alternatives.

You must either finish your homework now or wake up early tomorrow to do it.

This comprehensive understanding forms the foundation upon which more advanced grammatical structures and nuanced expressions are built, making it a vital area of study for anyone seeking fluency and accuracy in the English language.
Mastering the usage of this particular determiner requires a comprehensive understanding of its various grammatical roles and the specific contexts in which it operates most effectively. The most fundamental rule to remember is that it almost exclusively deals with two items, people, or possibilities. When you are constructing a sentence to present a choice between two distinct options, this word is your primary grammatical tool. It can be placed directly before a singular countable noun to indicate that one or the other of the two items is acceptable or relevant. This is known as its determiner function, and it is incredibly common in everyday speech and writing.

You may sit in either chair, as they are both completely comfortable.

In this structure, the noun following the determiner must be singular. This is a strict grammatical rule that learners often overlook, leading to common errors.
Singular Noun Rule
Always use a singular noun immediately after the determiner form of this word to maintain grammatical correctness.
However, the word's utility extends far beyond simple noun modification. It frequently functions as a pronoun, standing in for a previously mentioned pair of items or individuals. When used as a pronoun, it allows for more concise and fluid communication by avoiding unnecessary repetition.

I looked at two different cars today, but I did not buy either.

In this example, the pronoun seamlessly replaces the phrase 'either car', demonstrating its efficiency. Another highly significant usage pattern involves its role as a correlative conjunction, where it is invariably paired with the word 'or'. This powerful combination is used to link two alternatives, emphasizing that the choice is strictly limited to the presented options. Parallelism is crucial here for stylistic elegance and clarity. If a verb follows the first part, a verb should follow the second part.

We can either eat at the restaurant or order food to be delivered to the house.

Furthermore, the word plays a unique and essential role in expressing negative agreement. When someone makes a negative statement, and you wish to express that the same negative condition applies to you, you place this word at the very end of your response.
End Position Agreement
In negative agreements, the word must be placed at the absolute end of the clause or sentence.
This usage is particularly prevalent in spoken English and is vital for natural-sounding conversations.

She cannot swim, and her brother cannot swim either.

It is also worth discussing the construction 'either of', which is used before plural pronouns (us, them, you) or plural nouns preceded by a determiner (the, these, those, my). This specific construction allows speakers to refer to one of a specific, identified pair.
Prepositional Phrase Usage
The phrase 'either of' must be followed by a plural noun phrase or a plural object pronoun.

Has either of you seen my misplaced keys this morning?

By carefully studying and practicing these diverse usage patterns, learners can integrate this versatile word into their vocabulary with confidence and precision, significantly elevating their overall language proficiency.
The ubiquitous nature of this word means that you will encounter it in virtually every conceivable context where the English language is spoken or written. Its primary function of presenting choices and indicating duality makes it an indispensable part of human communication, as our daily lives are fundamentally structured around making decisions between alternatives. In casual, everyday conversation, it is frequently heard when people are making plans, offering food or drinks, or discussing preferences. Imagine a scenario where two friends are deciding what to do on a weekend; this word will almost certainly make an appearance as they weigh their options.

We can go to the beach or the mountains; either destination sounds wonderful to me.

Beyond informal settings, it is equally prevalent in professional and academic environments. In business meetings, negotiations, and formal presentations, it is used to outline different strategies, propose alternative solutions, or delineate mutually exclusive outcomes.
Professional Context
Used to present strategic alternatives or binary choices in business negotiations and formal reports.
The clarity and precision it offers are highly valued in these contexts, where ambiguity can lead to costly misunderstandings.

The company must either increase its revenue immediately or face severe budget cuts next quarter.

You will also frequently hear it in the realm of customer service and retail. When a customer is presented with options regarding products, payment methods, or delivery times, the staff will often utilize this word to clearly define the available choices. Furthermore, it is a staple in literature, journalism, and broadcasting. Writers and journalists rely on it to construct balanced sentences, contrast different viewpoints, and create rhetorical emphasis.
Literary Usage
Employed by authors to create tension, highlight dilemmas, or establish parallel structures in narratives.
In news reports, it might be used to describe the possible outcomes of a political event or a legal trial.

The jury will return with a verdict of either guilty or not guilty by tomorrow morning.

In the context of negative agreements, you will hear it constantly in social interactions as people seek to build rapport and find common ground by sharing aversions or inabilities. This specific usage is a key marker of conversational fluency.

I have never been to Paris, and my husband hasn't either.

Finally, it is important to recognize that the pronunciation of the word can vary significantly depending on the geographical region. In American English, it is predominantly pronounced with a long 'e' sound (EE-ther), while in British English, the pronunciation with a long 'i' sound (EYE-ther) is much more common.
Regional Pronunciation
Be prepared to hear both 'EE-ther' and 'EYE-ther' depending on whether you are consuming American or British media.
However, both pronunciations are universally understood across the English-speaking world, and neither is considered incorrect.

You can pronounce it either way, and everyone will still understand exactly what you mean.

By actively listening for this word in these diverse contexts, learners can develop a more intuitive grasp of its multifaceted applications and nuances.
Despite its frequent appearance in everyday English, this word is the source of several common and persistent errors for language learners, primarily due to its specific grammatical constraints and its interaction with other words in a sentence. One of the most frequent mistakes involves the failure to adhere to the strict rule regarding singular nouns. When the word is used directly as a determiner, it must absolutely be followed by a singular countable noun, never a plural one. This is because the word inherently singles out one item from a pair, focusing on the individual components rather than the collective group.

Incorrect: You can take either buses to get to the city center.

The correct formulation requires the singular form of the noun.
Correction Strategy
Always double-check the noun immediately following the determiner to ensure it is in its singular form.
Another major area of confusion arises when learners attempt to use the word to refer to more than two options. The word is strictly binary; it is designed to handle pairs. If a situation involves three, four, or more choices, using this word is semantically incorrect and can lead to significant confusion.

Incorrect: You can choose either of the five colors available.

Furthermore, learners often struggle with subject-verb agreement when using the construction 'either of' followed by a plural noun phrase. While the noun phrase is plural, the formal grammatical rule dictates that the verb should be singular, as the subject of the sentence is technically the singular pronoun 'either'.
Subject-Verb Agreement
In formal writing, use a singular verb after 'either of + plural noun', though plural verbs are often accepted in casual speech.

Formal: Either of the candidates is highly qualified for the position.

Another prevalent mistake occurs in the context of negative agreements. Learners sometimes incorrectly use 'too' or 'also' at the end of a negative sentence, instead of the correct word.

Incorrect: I don't like mushrooms, and he doesn't like them too.

Finally, when using the correlative conjunction pair, learners frequently violate the rule of parallel structure. The grammatical elements following both parts of the conjunction must be identical in form to ensure clarity and stylistic balance.
Parallel Structure
Ensure that the words or phrases following the first part of the conjunction match the grammatical form of those following the second part.

Incorrect: You must either wash the dishes or to vacuum the floor.

By consciously avoiding these common pitfalls, learners can significantly improve the grammatical accuracy and natural flow of their English communication, demonstrating a higher level of linguistic competence.
Navigating the English language requires a keen understanding of words that share similar meanings or grammatical functions, as choosing the precise word can significantly alter the nuance and accuracy of a sentence. When considering our target word, several other terms immediately come to mind, each with its own specific rules and subtle distinctions. The most direct counterpart is its negative equivalent, 'neither'. While our target word presents a choice where one option is viable, 'neither' explicitly negates both options, indicating that not one and not the other is acceptable or true.

I offered him tea or coffee, but he wanted neither beverage.

Understanding the relationship between these two words is fundamental, as they form a binary system of affirmation and negation regarding pairs of items.
Negative Counterpart
Use 'neither' when you want to reject both options presented in a pair, effectively meaning 'not either'.
Another closely related word is 'both'. While our target word singles out one item from a pair, 'both' encompasses the entire pair, indicating that the two items are included together in the statement.

She is fluent in both French and Spanish.

This distinction is crucial because confusing the two can completely change the intended meaning of a sentence from an exclusive choice to an inclusive combination. Furthermore, when dealing with choices that exceed a pair, the word 'any' becomes the necessary substitute. As previously discussed, our target word is strictly limited to two options. If a situation presents three or more possibilities, 'any' must be employed to indicate that one item from the larger group is acceptable.
Multiple Options
Switch to 'any' when the number of choices expands beyond two, maintaining the concept of selecting a single option.

You can pick any of the ten books on the shelf.

In the context of conjunctions, the pair 'whether...or' functions similarly to our target correlative pair, but it introduces a condition or an indirect question rather than a direct choice between two distinct actions or objects.

I do not know whether it will rain or snow tomorrow.

Lastly, in the specific realm of negative agreements, the word 'too' serves as the affirmative counterpart. While our target word is used to agree with a negative statement, 'too' is used to agree with a positive statement.
Affirmative Agreement
Use 'too' at the end of a sentence to show agreement with a previously stated positive fact or opinion.

She loves chocolate, and I love it too.

By carefully distinguishing between these similar words and understanding their specific applications, learners can communicate with greater precision, clarity, and grammatical correctness, ensuring their intended meaning is always accurately conveyed.

  • Using 'too' instead of 'either' for negative agreement (e.g., 'I don't like it too' instead of 'I don't like it either').
  • Failing to maintain parallel structure in 'either...or' sentences (e.g., 'Either wash the car or to cut the grass').
  • Using a plural verb after 'either of' in formal writing contexts (e.g., writing 'Either of the answers are correct' instead of 'is correct').

小贴士

Singular Nouns Only

When placing the word directly before a noun, always ensure the noun is singular. Say 'either book', never 'either books'. This is a very common mistake that is easy to fix.

The Rule of Two

Always count your options before using this word. If you have exactly two, you are safe to use it. If you have three, four, or more, you must switch to using the word 'any'.

Negative Agreement

When agreeing with a negative statement (like 'I don't know'), always put this word at the very end of your sentence ('I don't know either'). Never use 'too' for negative agreement.

Pick Your Pronunciation

Don't stress over EE-ther vs. EYE-ther. Both are 100% correct. Listen to the English speakers around you or the media you consume, pick the one you like best, and use it consistently.

Balance Your Sentences

When using 'either...or', make sure the two parts of your sentence are balanced. If you put a verb after 'either', put a verb after 'or'. This makes your English sound much more natural and advanced.

Subject-Verb Agreement

In formal essays or business emails, treat 'either' as a singular subject. Write 'Either of the plans is acceptable', using 'is' instead of 'are', even though 'plans' is plural.

Learn the Opposites

To fully master this word, you must also master its opposite, 'neither'. Practice changing sentences from positive choices ('either...or') to negative rejections ('neither...nor').

Listen for the 'Or'

When listening to fast native speech, if you hear the word 'either', immediately start listening for the word 'or' later in the sentence. This will help you understand the two choices being presented.

Master 'Either Way'

Learn the phrase 'either way'. It's incredibly useful in conversation to show that a decision doesn't matter because the outcome is the same. 'We can stay or go; either way, I'm happy.'

Check Your Pronouns

If you use 'either of', make sure the pronoun that follows is plural. Say 'either of us', 'either of them', or 'either of you'. Never say 'either of it' or 'either of him'.

记忆技巧

Remember 'E' for 'Exactly two'. If you have Exactly two choices, use Either.

词源

Old English

文化背景

The most prominent cultural note is the pronunciation. Americans predominantly say 'EE-ther', while the British predominantly say 'EYE-ther'. Both are universally understood.

In informal speech, people often say 'me either' to agree with a negative statement, though 'me neither' is technically more grammatically correct and preferred in formal contexts.

No, you cannot. The word 'either' is strictly used when there are exactly two options. If you have three or more choices, you should use the word 'any'. For example, if there are three shirts, say 'You can choose any of the shirts', not 'either of the shirts'.

Both pronunciations are completely correct and widely understood. 'EE-ther' is more common in American English, while 'EYE-ther' is more common in British English. You can choose whichever pronunciation you find easier to say. Consistency is more important than which one you choose.

In formal writing, you should use a singular verb after 'either of' (e.g., 'Either of the candidates is qualified'). However, in casual, everyday speech, it is very common to hear native speakers use a plural verb (e.g., 'Either of the candidates are qualified'). For tests and essays, stick to the singular verb.

'Either' presents a choice where one of two options is acceptable or true (e.g., 'You can have either tea or coffee'). 'Neither' means that not one and not the other option is acceptable or true (e.g., 'I want neither tea nor coffee'). They are opposites in the context of binary choices.

You use 'either' to agree with a negative statement. If someone says 'I don't like cold weather', you can agree by saying 'I don't like it either'. The word must be placed at the very end of your negative sentence. Do not use 'too' in this situation.

Generally, no. It means one or the other. However, there is a specific exception in phrases describing position, such as 'There are trees on either side of the river'. In this specific context, it effectively means 'on both sides'.

When 'either' is used directly before a noun as a determiner, that noun must be singular. Because 'either' singles out one option from a pair, the grammar requires the singular form. The correct sentence is 'You can take either bus'.

Parallel structure means that the grammar following 'either' must match the grammar following 'or'. If 'either' is followed by a noun, 'or' must be followed by a noun (e.g., 'either a cat or a dog'). If it's followed by a verb, 'or' needs a verb (e.g., 'either run or walk').

Yes, absolutely. You can start a sentence with 'Either' when it functions as a determiner or pronoun acting as the subject. For example, 'Either day works for me' or 'Either of the options is fine'. You can also start with the conjunction: 'Either you leave now, or I will call the police'.

'Either way' is a common phrase that means whatever choice is made between two options, the final result or situation will be the same. For example, 'We can drive or take the train; either way, we will arrive at 5 PM'.
