/that’s/

The word that’s is one of the most ubiquitous contractions in the English language, serving as a linguistic bridge that connects a demonstrative pronoun with a vital verb. Primarily, it functions as a shortened form of that is, but it also frequently stands in for that has. Its primary purpose is efficiency; in natural speech and informal writing, English speakers prefer the rhythmic flow of a single syllable over the staccato nature of two distinct words. When we use that’s, we are usually pointing—either physically or metaphorically—to an idea, an object, or a situation that has already been established in the conversation. It acts as a focal point, drawing the listener's attention to a specific state of being or a completed action.

Identification

Used to identify a specific person, place, or thing that is being pointed out. For example, 'That’s my car' identifies the object in the speaker's field of vision.

Definition of State

Used to describe the quality or condition of something previously mentioned. If someone describes a long journey, the listener might respond, 'That’s exhausting,' where 'that' refers to the entire concept of the trip.

Beyond simple identification, that’s plays a crucial role in logical progression. It often introduces a conclusion or a consequence. In a debate, a speaker might say, 'If we spend all our money now, we won't have any for the emergency; that’s why we need to save.' Here, the contraction encapsulates the preceding logic and prepares the listener for the 'why'. This versatility makes it an essential tool for B1 learners who are moving beyond simple sentences into more complex, cohesive discourse. It allows for a smoother transition between thoughts, making the speaker sound more fluent and less robotic. It is also important to note the 'that has' variation, which is used in the present perfect tense. For example, 'That’s been a problem for years' (That has been...). This usage is slightly more advanced but equally common in everyday interactions.

The 'That Has' Function

In sentences like 'That’s been done already,' the 's' stands for 'has'. This is common in passive voice or present perfect constructions referring to an abstract 'that'.

Ultimately, that’s serves as a linguistic glue. It takes the weight of a previous sentence and carries it forward into a new observation. Whether you are expressing surprise, confirming a fact, or describing a situation, this contraction is your go-to tool for maintaining a natural, conversational pace in English. Understanding its dual role as both 'is' and 'has' is a hallmark of reaching the B1 threshold, allowing for more nuanced expression of time and state.

Using that’s correctly requires an understanding of its syntactic role as a subject-verb combination. Because it contains a verb, it cannot function as a simple noun phrase; it must be the core of a clause. Most commonly, that’s is followed by an adjective, a noun phrase, or a prepositional phrase. This structure allows the speaker to provide immediate feedback or categorization of an idea. For example, in the sentence 'That’s interesting,' the contraction links the subject (the idea) to the predicate (the quality of being interesting). This is the most basic building block of conversational English.

With Adjectives

The most frequent usage. 'That’s great,' 'That’s tough,' 'That’s impossible.' It provides a quick reaction to news or statements.

With Noun Phrases

Used for identification or classification. 'That’s a tall building,' 'That’s my brother over there,' 'That’s a valid point.'

Another sophisticated way to use that’s is in combination with 'why', 'how', 'where', or 'when'. These are known as cleft-like constructions or identifying clauses. For instance, 'That’s why I called you' explains the reason for an action. 'That’s how it works' explains a process. These structures are vital for B1 learners because they help in organizing thoughts logically during a conversation. Instead of saying 'I called you because of that,' which sounds slightly clunky, 'That’s why I called you' sounds much more native and fluid. It places the emphasis on the reason, which is usually what the listener is interested in.

The Present Perfect Usage

When 's' means 'has', it is followed by a past participle. 'That’s been decided' means 'That has been decided'. This is used for events that have a present relevance.

When using that’s in negative sentences, the 'not' follows the contraction: 'That’s not right.' While 'That isn't' is also possible, 'That’s not' is often preferred for its emphasis on the negation. Mastering these patterns—adjective follow-ups, identifying clauses, and present perfect links—will significantly enhance your ability to participate in dynamic English conversations. It allows you to react quickly and accurately to the world around you.

You will hear that’s everywhere, from the bustling streets of London to the boardrooms of New York, and in almost every movie or podcast you consume. It is the default way to refer to an idea in motion. In casual conversation, it acts as a constant feedback loop. When friends talk, you’ll hear 'That’s crazy!' or 'That’s true' every few seconds. It serves as a social signal that the listener is following the story. In professional settings, it is used to summarize points: 'That’s the main goal for this quarter.' Its frequency is so high that native speakers often blend the 'th' and 's' sounds into a very sharp, quick burst, sometimes almost sounding like 'ts' in very rapid speech.

In Media

News anchors use it to transition: 'That’s the latest from the capital.' Movie characters use it for dramatic realization: 'So, that’s where you’ve been hiding!'

In Customer Service

You will hear it when confirming orders or details. 'That’s one large coffee, right?' or 'That’s twenty dollars, please.'

In the digital age, that’s is the king of text messaging and social media comments. Because it’s short and punchy, it fits perfectly in a tweet or a quick WhatsApp reply. You’ll see it in memes ('That’s what she said') and in YouTube titles ('That’s how I lost 10 pounds'). It is also a staple of storytelling. When someone recounts a sequence of events, they use that’s to mark the climax or the turning point: '...and then he opened the door, and that’s when I saw him.' This usage creates a sense of immediacy and draws the listener into the moment, making the narrative more engaging.

In Education

Teachers use it to validate students: 'That’s exactly right!' or to correct them: 'That’s not quite what the book says.'

Whether you are listening to a song lyric or a scientific lecture, that’s is the connective tissue of English. It is so common that its absence often makes speech sound overly formal or even robotic. For a B1 learner, hearing and using that’s naturally is a major step toward sounding like a native speaker. It shows that you are not just translating word-for-word, but that you are adopting the natural rhythms and shortcuts of the language.

Even though that’s is a simple contraction, it is a frequent source of errors for both learners and native speakers. The most common mistake is the confusion between 'that’s' and 'thats'. In English, 'thats' without an apostrophe is almost never a correct word. Unlike 'its' (possessive) and 'it's' (contraction), 'that' does not have a possessive form that drops the apostrophe. If you mean 'that is' or 'that has', you must use the apostrophe. This is a very common typo in emails and text messages, but in formal writing, it is considered a significant grammatical error.

The 'Thats' Error

Writing 'thats' instead of 'that’s'. Remember: 'that's' is always a contraction. There is no possessive 'thats'.

Plural Confusion

Using 'that’s' for plural objects. Incorrect: 'That’s my parents.' Correct: 'Those are my parents.' 'That’s' is strictly singular.

Another common mistake involves the 'that has' contraction. Learners often forget that 'that’s' can mean 'that has' and instead try to say 'that’s had' or 'that’s been' without realizing the 's' already covers the 'has'. Furthermore, some learners confuse 'that’s' with 'it’s'. While they are often interchangeable, 'that’s' is more demonstrative—it points to something specific—while 'it’s' is more general. For example, if someone tells you a story, saying 'That’s interesting' refers specifically to the story they just told. Saying 'It’s interesting' is a bit more detached. Using 'it’s' when you should use 'that’s' can sometimes make you sound less engaged in the conversation.

Overuse of 'That's'

Using 'that's' to start every sentence can make your speaking sound repetitive. Try to vary your sentence starters with 'This is' or 'It is'.

Finally, be careful with the contraction in questions. While 'That’s right?' is common in very informal speech as a tag-like question, the standard form is 'Is that right?'. Using the contraction in the wrong place in a question can make you sound less fluent. By paying attention to these common pitfalls—especially the apostrophe and the singular/plural distinction—you will avoid the most frequent errors associated with this essential English word.

While that’s is incredibly useful, it is not always the best choice. Depending on the context, words like 'it’s', 'this is', or 'which is' might be more appropriate. Understanding the subtle differences between these alternatives is key to achieving a higher level of English proficiency. 'That’s' is demonstrative—it points 'away' from the speaker toward something already mentioned. In contrast, 'this is' often points to something the speaker is currently introducing or something physically close to them. 'It’s' is the most neutral and is used when the subject is already well-established and doesn't need to be 'pointed at' anymore.

That’s vs. It’s

'That’s' is for emphasis and reaction ('That’s amazing!'). 'It’s' is for general description ('It’s raining'). Use 'that’s' when you want to highlight the specific thing you are talking about.

That’s vs. This is

'This is' is for things here and now. 'That’s' is for things over there or things just said. 'This is my phone' (in my hand); 'That’s your phone' (on the table).

In more formal or complex sentences, you might use 'which is' as a relative clause. For example, 'He bought a new car, which is very expensive.' You cannot use 'that’s' in this specific relative clause structure (you wouldn't say 'He bought a new car, that’s very expensive' as a single sentence, though you could as two separate sentences). Another alternative is 'there is', which indicates existence rather than identification. 'There is a problem' (a problem exists) vs. 'That’s a problem' (the thing we just discussed is a problem). Choosing the right one changes the focus of your sentence.

Formal Alternatives

In academic papers, use 'This indicates that...' or 'Such a situation is...' instead of starting a sentence with 'That’s'.

By exploring these alternatives, you gain a deeper understanding of English deixis—the way language points to things in time and space. While that’s is a powerful and versatile tool, knowing when to use 'it’s' for neutrality or 'this is' for proximity will make your English much more precise and sophisticated. Practice swapping them in your mind to see how the meaning or emphasis of the sentence changes.
