But vs. However: What's the Difference?

Punctuation is key: but is for short connections, however for more formal, significant contrasts.

Grammar Rule in 30 Seconds

Use 'but' to join two ideas in one sentence, and 'however' to start a new, more formal sentence.

  • Use 'but' with a comma to connect two clauses: 'I'm tired, but I'm working.'
  • Use 'however' at the start of a new sentence followed by a comma.
  • Never use 'however' as a simple replacement for 'but' between two commas.
Idea A + , but + Idea B ↔️ Idea A. However, + Idea B.

Overview

Both but and however serve to introduce information that contrasts with or qualifies a preceding statement. While their ultimate function is similar—to signal a shift in thought or an opposing idea—they operate differently at a grammatical level and convey distinct levels of formality and emphasis. Understanding these distinctions is crucial for B1 learners aiming for precision and naturalness in English communication.

But acts as a coordinating conjunction, connecting two grammatically equal parts within a single sentence. Conversely, however functions as a conjunctive adverb, bridging ideas between sentences or independent clauses with a stronger, often more formal, sense of transition. Mastering their usage allows you to navigate the nuances of expressing contrast, ensuring your writing and speech are both grammatically correct and contextually appropriate.

A precise grasp of their application is not merely about avoiding errors, but about enhancing the clarity and sophistication of your communication, enabling you to articulate complex relationships between ideas with greater accuracy.

How This Grammar Works

The fundamental difference between but and however lies in their grammatical classifications and the structural implications of those classifications. Recognizing whether a word is a conjunction or an adverb is key to applying the correct punctuation and achieving the intended flow of ideas. This distinction is rooted in the very fabric of English sentence construction.
Coordinating Conjunctions: The Case of but
But belongs to a small, closed class of words known as coordinating conjunctions (often remembered by the acronym FANBOYS: for, and, nor, but, or, yet, so). A coordinating conjunction's primary role is to connect two grammatically equivalent elements. When but connects two independent clauses, it indicates a direct contrast or an exception to the preceding statement.
Each of these independent clauses possesses a subject and a verb and can stand alone as a complete sentence, but but unites them into a single, cohesive thought—a compound sentence. This grammatical linkage suggests a close, immediate relationship between the two contrasting ideas, implying that they are presented as a single unit of information that should be processed together. The comma before but signals a slight pause, integrating the contrast smoothly into the preceding idea.
  • She prepared extensively for the exam, but the questions were unexpectedly difficult. (The effort and the outcome are closely tied as one compound idea.)
  • They planned a beach vacation, but heavy rains forced them indoors. (The plan and the hindrance are presented as a single narrative event, where the latter alters the former.)
  • I appreciate your offer, but I've already made other arrangements. (The gratitude and the refusal are part of one polite statement, expressing a polite contradiction.)
The use of but creates a compound sentence, where the contrast is presented as an integral part of the initial thought. This creates a smooth, continuous flow, making but suitable for a wide range of contexts, from informal conversation to formal writing, provided the ideas are closely linked and the contrast is not overwhelmingly dramatic. It often conveys a sense of slight opposition or an exception that doesn't completely undermine the preceding statement, maintaining a sense of continuity in thought.
Conjunctive Adverbs: The Role of however
However functions as a conjunctive adverb. Unlike coordinating conjunctions, conjunctive adverbs do not join clauses in the same way. Instead, they act as adverbs, modifying an entire clause by showing its logical relationship (in this case, contrast or concession) to a preceding clause or sentence.
They indicate a conceptual bridge between two separate thoughts. Because however is an adverb, it has greater flexibility in its placement within the clause it modifies, though its most common and impactful position for contrast is at the beginning of the clause. This adverbial nature necessitates stronger punctuation (semicolons or periods) to signal the more pronounced transition it introduces, often creating a more noticeable pause.
  • The project faced several unforeseen obstacles; however, the team managed to meet the deadline. (The obstacles and the achievement are distinct points that are being conceptually linked.)
  • Many students struggle with advanced calculus. However, consistent practice can lead to significant improvement. (The struggle and the solution are presented as separate, yet connected, pieces of information that build upon each other.)
  • The initial market research suggested strong demand for the product. The launch, however, yielded disappointing sales figures. (Here, however is placed parenthetically, modifying the clause and highlighting the contrast within it, offering a qualification to the preceding statement.)
The distinction is subtle but significant. While but integrates the contrast directly into the initial statement, creating a single grammatical unit, however introduces the contrasting idea as a separate, yet related, thought. This separation often lends however a more emphatic and formal tone, signaling a more deliberate shift in argument or discussion.
It allows the reader or listener to pause and fully process the first idea before being presented with the contrasting one, making the contrast itself more prominent. This also reflects a rhetorical choice to present the contrasting idea as a new, distinct point rather than an appendage to the previous one.
Degrees of Contrast and Expectation
Beyond grammar, but and however also subtly differ in the type or degree of contrast they typically introduce, influencing the implied expectation. This nuance is critical for sophisticated communication.
  • But often signals a mild or expected contrast**, or an exception that doesn't completely negate the first statement. It frequently implies a slight deviation from an otherwise assumed continuity. For example, I wanted to go, but I was tired implies a simple and common reason for not going. The expectation might have been for the person to go, and tiredness presents a straightforward, understandable reason for the deviation. It smoothly transitions to a common, often less surprising, counterpoint.
  • However frequently introduces a stronger, more significant, or perhaps unexpected contrast**. It can signal a more substantial divergence from what might be anticipated based on the preceding information, sometimes even presenting a contradictory idea. The scientific community was confident in their initial findings. However, subsequent experiments failed to replicate the results highlights a profound and potentially surprising contradiction that significantly alters the understanding of the initial findings. This implies a more dramatic shift in understanding or outcome, often requiring more cognitive processing from the audience. This higher degree of emphasis makes however particularly useful in contexts where you need to clearly demarcate a shift in argument or evidence, or introduce a major qualification.
This difference in implied expectation contributes to however's more formal and academic feel. It is often employed to present counter-arguments, qualifications that significantly alter meaning, or surprising outcomes, where a greater emphasis on the contrasting element is desired, and a clear break in thought is rhetorically effective.

Formation Pattern

1
The distinct grammatical roles of but and however dictate their specific punctuation and sentence structures. Adhering to these patterns is essential for clarity and grammatical correctness at the B1 level and beyond. Punctuation serves as a critical guide for the reader, signaling the relationship between ideas.
2
Using but (Coordinating Conjunction)
3
When but connects two independent clauses, it is almost always preceded by a comma. This creates a compound sentence structure, maintaining a smooth, continuous flow of thought.
4
| Structure | Example | Explanation |
5
| :----------------------------------------- | :--------------------------------------------------- | :---------------------------------------------------------------------------------- |
6
| Independent Clause 1, but Independent Clause 2. | She wanted to travel, but she couldn't afford it. | She wanted to travel and she couldn't afford it are both complete sentences. but joins them, with a comma preceding it. |
7
| | He loves spicy food, but his stomach can't handle it. | This structure creates a compound sentence, presenting two closely related, contrasting ideas as one unit. |
8
| | I enjoy reading novels, but I rarely find the time. | The comma is crucial here to separate the two independent clauses effectively, preventing a run-on sentence. |
9
Note: If but connects two phrases or dependent clauses (not two full independent clauses), a comma is generally not used: She is intelligent but sometimes stubborn. or He tried hard but failed. In this article, our focus is on but as a connector of independent clauses where it contrasts two main ideas, as this is where confusion with however typically arises.
10
Using however (Conjunctive Adverb)
11
However offers more flexibility in its use, but it always requires stronger punctuation to indicate its adverbial function and the more pronounced transition it signals. The choice of punctuation depends on whether you are linking two clauses within one sentence or two separate sentences.
12
Option 1: Connecting two independent clauses within a single sentence
13
When however connects two independent clauses that are closely related in meaning, a semicolon (;) is used before however, and a comma (,) is used after it. This structure signifies a stronger break than but but maintains the clauses within a single sentence, often for rhetorical effect where a linked, yet distinctly contrasting, thought is intended.
14
| Structure | Example | Explanation |
15
| :---------------------------------------------------- | :------------------------------------------------------------------------------- | :---------------------------------------------------------------------------------- |
16
| Independent Clause 1; however, Independent Clause 2. | The weather was predicted to be sunny; however, it rained all afternoon. | The semicolon separates the two independent clauses, indicating a strong but connected break, and however begins the second clause, preceded and followed by punctuation. |
17
| | Sales figures increased dramatically last quarter; however, profitability remained flat. | This conveys a significant, often unexpected, contrast between the two linked ideas, emphasizing the discrepancy. |
18
| | The experiment produced promising initial results; however, further testing is required. | The semicolon ensures a grammatically correct transition between the two independent thoughts, highlighting the conditional nature of the initial results. |
19
Option 2: Connecting two separate sentences
20
This is perhaps the most common and often most formal use of however. When however begins a new sentence that contrasts with the preceding one, it is preceded by a period, and followed by a comma. This creates a distinct separation between the two contrasting ideas, giving greater emphasis to the shift and allowing each sentence to stand as a complete, independent thought before the transition.
21
| Structure | Example | Explanation |
22
| :------------------------------------------ | :------------------------------------------------------------------------------ | :---------------------------------------------------------------------------------- |
23
| Independent Clause 1. However, Independent Clause 2. | The company invested heavily in new technology. However, their market share continued to decline. | The period creates a full stop, making the contrast introduced by However more prominent and giving it greater weight. |
24
| | She understood the theory perfectly. However, she struggled with practical application. | This structure emphasizes the break and the significance of the contrasting information, highlighting a specific challenge. |
25
| | The team worked tirelessly to prepare. However, unforeseen technical issues arose during the presentation. | The capital 'H' and subsequent comma reinforce However as a transitional element opening a new, contrasting thought. |
26
Option 3: Mid-sentence (Parenthetical use for emphasis/qualification)
27
Less frequently for direct contrast between two independent clauses, but however can be placed parenthetically within a clause to add emphasis or a subtle qualification to a single idea. In this case, it is typically set off by commas on both sides. This usage doesn't directly connect two clauses but rather modifies the statement it's within, often providing a concession or a nuanced point.
28
The decision, however, was met with considerable opposition. (Here, however modifies the decision was met, indicating a qualification to an unstated or previously stated expectation of consensus.)
29
Many challenges, however, remain to be addressed before the project can proceed. (Expressing a concession or a point of resistance within the current discussion.)
30
This third option, while grammatically valid, is distinct from but and the primary however usage for connecting contrasting independent clauses. Learners should prioritize mastering the first two options for expressing direct contrast between main ideas, as they are the most common points of confusion.
31
Summary of Punctuation for Contrast
32
Understanding this table will help you correctly punctuate sentences involving but and however when expressing contrast between independent clauses or sentences.
33
| Connector | Grammatical Role | Punctuation | Example |
34
| :-------- | :--------------------- | :------------------------------------------------- | :------------------------------------------------------------------------------- |
35
| but | Coordinating Conjunction | , but between independent clauses | I wanted to go, but I was busy. |
36
| however | Conjunctive Adverb | ; however, between independent clauses | I wanted to go; however, I was busy. |
37
| however | Conjunctive Adverb | . However, at the start of a new sentence | I wanted to go. However, I was busy. |
38
| however | Conjunctive Adverb | , however, within a clause (parenthetical) | My decision, however, was final. (Note: modifies within a clause, not connecting two.) |

When To Use It

Choosing between but and however is not merely a matter of grammatical correctness; it also involves considerations of formality, emphasis, and stylistic preference. Your choice influences the tone, impact, and overall flow of your communication, subtly guiding your audience's interpretation of the relationship between ideas.
Use but when:
  • For direct and mild contrasts within a single sentence: But is the natural choice when the two opposing ideas are closely linked and part of a continuous thought. It implies a simpler, less emphatic opposition, often serving to explain or qualify a preceding statement. The contrast is integrated into the flow without a significant break.
  • The restaurant was cheap, but the portions were small. (A common observation where both ideas contribute to a single assessment of the restaurant.)
  • She understood the instructions, but she still made a few mistakes. (The contrast between understanding and execution is a continuous thought.)
  • In casual and informal contexts: Conversations, personal emails, texts, and social media posts often favor but for its brevity and natural flow. It reflects how native speakers typically express minor shifts or exceptions in a relaxed, everyday register.
  • I'd love to help, but I'm swamped right now. (A common, polite refusal in a casual text message.)
  • The game was fun, but the ending was disappointing. (A quick, unforced critique in casual conversation.)
  • To introduce an exception or qualification that is not a strong contradiction: But can signal a slight limitation or a piece of information that makes the preceding statement less absolute, without implying a major counterpoint.
  • Everyone attended the meeting but Sarah. (Sarah is the sole exception to the general statement.)
  • He is good at math, but he struggles with geometry. (Identifying a specific area of difficulty within a broader competence.)
  • When the clauses are relatively short and easily digestible together: The comma before but provides a brief pause, allowing for a smooth, uninterrupted transition between two concise, contrasting points, maintaining sentence rhythm.
Use however when:
  • For more formal or academic writing: In essays, research papers, business reports, and professional emails, however lends a more sophisticated and intellectual tone. It signals a considered transition and a more robust presentation of contrasting arguments, aligning with conventions of formal discourse.
  • The preliminary data indicated a positive trend. However, further analysis revealed significant statistical anomalies. (Used to introduce a critical finding that challenges initial optimism in an academic report.)
  • We appreciate your detailed proposal. However, the budget constraints require us to seek a more cost-effective solution. (A professional and polite way to introduce a significant hurdle in a business email.)
  • To introduce a significant or unexpected contrast: However emphasizes the opposing idea more strongly than but. It suggests a more substantial shift in direction, a deliberate counter-argument, or a surprising turn of events, giving the contrasting idea more prominence.
  • The company launched an aggressive marketing campaign; however, consumer interest remained low. (A strong, unexpected contrast between effort and outcome, highlighting a market failure.)
  • Many believe that technology simplifies life. However, it can also introduce new complexities and dependencies. (A deliberate counter-point in an analytical discussion, offering a nuanced perspective.)
  • When connecting ideas across sentences or with a semicolon for a stronger break: As a conjunctive adverb, however is ideally suited for bridging more independent thoughts. This separation provides a greater pause and allows each idea to be considered more distinctly, making the logical connection more explicit.
  • The team spent months developing the software. However, a critical bug was discovered just before release. (A clear break highlights the severity of the discovery.)
  • The government implemented strict new regulations; however, their effectiveness in curbing pollution remains debatable. (Using a semicolon creates a strong link between two distinct but related propositions, emphasizing the unresolved issue.)
  • To add emphasis to the contrast: If you want to ensure the reader fully grasps the opposing nature of the information, however highlights this contrast more prominently. Its placement, particularly at the beginning of a new sentence, draws immediate attention to the subsequent contrasting statement, signaling its importance.
  • When however is used parenthetically mid-sentence: This particular usage, set off by commas, adds a nuanced qualification or slight correction to the statement it's embedded within, rather than directly joining two independent clauses. This provides a subtle way to acknowledge a counterpoint without disrupting the main clause's structure.
  • The committee's decision, however, was not unanimous. (Here, however clarifies or qualifies the decision by adding a crucial detail.)
  • The path to success, however challenging, is always clearer with a meticulously crafted plan. (Expressing a concession or qualification about the nature of the path itself.)
Cultural Insight: In formal English, especially academic writing, there's a strong preference for varying sentence structure and using precise transitional devices. However is often chosen over but at the beginning of a sentence or paragraph to mark a clear rhetorical shift. While starting a sentence with but is grammatically acceptable and common in informal speech, it can be perceived as less sophisticated or less authoritative in highly formal written contexts.
This is a stylistic convention that reflects a desire for greater formality and explicit logical structuring in academic discourse.

Common Mistakes

Even advanced learners occasionally stumble when distinguishing but and however, primarily due to their similar functions but divergent grammatical requirements. Awareness of these common pitfalls can significantly improve your accuracy and the clarity of your communication.
  1. 1Incorrect Punctuation with however: This is arguably the most frequent error, often leading to a comma splice. Learners frequently treat however like but, preceding it with only a comma when connecting independent clauses. This misunderstanding stems from overlooking however's role as a conjunctive adverb rather than a coordinating conjunction.
  • Incorrect: I enjoyed the film, however I found the ending confusing.
  • Why it's wrong: This is a comma splice because two independent clauses (I enjoyed the film and I found the ending confusing) are incorrectly joined by only a comma. However is an adverb; it does not have the grammatical power to connect independent clauses with just a comma. It requires stronger punctuation to indicate the boundary between the two distinct thoughts.
  • Corrected:
  • I enjoyed the film; however, I found the ending confusing. ✅ (Using a semicolon before however correctly separates the independent clauses, and the comma after however sets off the adverbial transition.)
  • I enjoyed the film. However, I found the ending confusing. ✅ (Using a period to create two separate sentences is also grammatically correct and often used for stronger emphasis on the break.)
  • Rule to remember: When however connects two independent clauses, it must be preceded by a semicolon or a period and followed by a comma. If it appears parenthetically within a clause (meaning it's embedded in one clause to add a qualification), it is set off by two commas, as in The results, however, were inconclusive.
  1. 1Starting a Sentence with But in Formal Writing: While grammatically permissible and common in spoken and informal written English, beginning a sentence with But can sometimes be considered less formal or less impactful in academic or professional contexts. This is more a stylistic concern than a grammatical error.
  • Informal (Acceptable): The study had some limitations. But it still provided valuable insights.
  • More Formal Alternatives:
  • The study had some limitations; however, it still provided valuable insights. (Uses a semicolon to link related thoughts formally.)
  • Although the study had some limitations, it still provided valuable insights. (Uses a subordinating conjunction for a more complex sentence structure.)
  • The study had some limitations, but it still provided valuable insights. (Keeps it as a single compound sentence.)
  • Why it matters: In formal writing, However offers a clearer, more emphatic transition when starting a new sentence. It signals a deliberate shift in argument, which is valued in academic discourse for its precision and structure. Avoiding initial But is thus a stylistic choice reflecting academic and professional conventions, rather than a strict grammatical prohibition. It shows a command of formal rhetorical devices.
  1. 1Overusing however in casual speech: While however is excellent for conveying formality and significant contrast, using it too frequently or in overly casual conversations can sound stilted, overly academic, or even pretentious. The formality of the word can create a disconnect with the informal register of the conversation.
  • Awkward: I'm hungry; however, I should probably finish this report first.
  • More Natural: I'm hungry, but I should probably finish this report first.
  • Why it's awkward: The formality of however clashes with the relaxed nature of the context. But flows more naturally in everyday conversation because it creates a less pronounced pause and integrates the contrasting thought more smoothly into the conversational stream.
  1. 1Misplacing however within a clause: Although however can be placed mid-clause (parenthetically), improper placement can disrupt readability and create an awkward sentence structure. Its most natural parenthetical positions are typically after the subject or at the end of the clause.
  • Awkward: The decision was, however, met with considerable, opposition from the stakeholders. (The comma placement is redundant and clunky.)
  • Better: The decision, however, was met with considerable opposition from the stakeholders. (Placed directly after the subject, clearly set off by commas.)
  • Why it matters: When used parenthetically, however should typically follow the element it modifies or be placed where it minimally interrupts the clause's core meaning. Setting it off with commas helps guide the reader through the subtle qualification without causing confusion or halting the sentence's rhythm unnecessarily.
By consciously applying the punctuation rules associated with however and considering the context and desired tone, you can overcome these common errors and use both but and however with precision and confidence in your English communication.

Real Conversations

Observing but and however in authentic communication demonstrates how native speakers adapt their usage to different contexts, from casual chats to formal exchanges. These examples highlight the practical application of the grammatical and stylistic principles discussed, showcasing their role in modern communication.

Casual Conversation / Texting:

In informal settings, but is overwhelmingly preferred for its directness, speed, and ease of integration into speech and rapid written communication. It maintains a natural, continuous flow.

- Dialogue 1 (Friends discussing weekend plans):

- A: Are you free to grab coffee tomorrow morning?

- B: I'd love to, but I have an early meeting. (Simple, direct reason for inability, seamlessly connected.)

- Dialogue 2 (Teammates after a sporting event):

- A: That was a tough loss for us.

- B: Yeah, but we played really well in the second half. (A quick counterpoint, acknowledging the loss but highlighting a positive aspect without a formal pause.)

- Text message from a colleague:

- The concert tickets are expensive, but it'll be worth it for this band! (Expressing a minor reservation followed by immediate justification, maintaining a single thought.)

Professional Email / Workplace Communication:

Here, the choice often depends on the level of formality and the impact you wish to convey. However signals a more structured, considered, and often more critical transition, while but can still be used for less formal internal communications.

- Email to a client (more formal):

- The initial proposal outlines several innovative solutions. However, the projected costs appear to exceed our current budget allocations. (Beginning a new sentence with a strong, formal contrast, carefully introducing a problem.)

- Meeting discussion (moderately formal):

- We've made significant progress on Phase One; however, we need to address the remaining resource constraints before commencing Phase Two. (Using a semicolon and however for a clear, yet connected, transition between two important points, signaling a required action.)

- Internal memo (parenthetical however):

- The new software update significantly improves system stability. Its implementation, however, will require temporary downtime for all users. (A qualification embedded within the sentence, providing important context without a hard stop.)

Academic / Formal Presentations:

In highly formal contexts like academic papers, research presentations, or detailed reports, however is almost exclusively used to introduce counter-arguments, significant qualifications, or shifts in evidence, particularly at the beginning of a sentence or paragraph. This emphasizes logical structure and intellectual rigor.

- Research Paper Excerpt:

- Previous studies have largely focused on the short-term effects of climate change. However, there is growing evidence suggesting more profound long-term ecological impacts that require further investigation. (A strong transition to a new line of argument, emphasizing a gap in previous research.)

- Conference Presentation:

- The theoretical model predicts a linear correlation between variables. Experimental data, however, indicates a more complex, non-linear relationship. (Using however parenthetically to highlight a discrepancy between theory and empirical observation.)

- Critical Analysis:

- While the author presents compelling anecdotal evidence, the statistical data does not fully support their conclusions; however, the qualitative insights remain valuable for future research. (A nuanced, multi-part contrast using both subordination and however, demonstrating a balanced critical perspective.)

These examples demonstrate that while both words express contrast, their appropriate usage is deeply intertwined with the context and the desired rhetorical effect. Choosing correctly enhances clarity, professionalism, and naturalness in your English communication, allowing you to tailor your message precisely to your audience and purpose.

Quick FAQ

These frequently asked questions address common points of confusion for learners regarding but and however, providing concise, authoritative answers grounded in grammatical principles.
  • Q: Can I always replace but with however?
  • A: No. While both express contrast, their grammatical roles are distinct. But is a coordinating conjunction, directly joining two independent clauses into one sentence (e.g., I like tea, but I prefer coffee). However is a conjunctive adverb, typically connecting two independent clauses or sentences with stronger punctuation (e.g., I like tea; however, I prefer coffee. or I like tea. However, I prefer coffee.). Using however where but is grammatically required would result in a comma splice, a significant grammatical error because however lacks the joining power of a conjunction.
  • Q: Is it grammatically incorrect to start a sentence with But?
  • A: Grammatically, no, it is not incorrect. Modern English usage widely accepts starting sentences with coordinating conjunctions like but, especially in informal and semi-formal contexts. However, in highly formal academic or professional writing, many stylistic guides still advise against it, favoring However or restructuring the sentence for a more formal tone and clearer logical flow. It is a stylistic preference rooted in rhetorical impact, not a strict grammatical prohibition. In these formal contexts, However is often perceived as more sophisticated for signaling a new, contrasting thought.
  • Q: What's the main difference in the feeling or tone conveyed by but versus however?
  • A: But typically conveys a more direct, often milder, and continuous contrast. It keeps the two ideas closely linked, creating a smooth transition. However signals a more distinct, often stronger, or more surprising contrast. It introduces a more noticeable pause and emphasizes the shift in thought, contributing to a more formal, deliberate, or assertive tone. This makes however suitable for impactful rhetorical shifts or introducing significant counter-points.
  • Q: Does however always need a comma after it?
  • A: When however functions as a conjunctive adverb expressing contrast (meaning

FAQ (8)

Yes, you can, especially in informal writing or speech. However, in very formal academic essays, it is better to use `However` or `Nevertheless`.

The comma signals a pause, showing that `however` is a transition word (conjunctive adverb) and not part of the subject or verb.

Yes, significantly. `But` is neutral and common in speech, while `however` is the standard for professional and academic writing.

Usually, no. It would be redundant. Choose the one that fits your punctuation and register.

A comma splice is when you join two full sentences with only a comma. Using `however` with just a comma (e.g., 'I'm tired, however I'm going') is a classic comma splice.

Yes! For example: 'The food was expensive. It was delicious, however.' This is common in spoken English.

If it is joining two independent clauses (full sentences), yes. If it is just joining two words (e.g., 'small but strong'), no comma is needed.

They are very similar, but `nevertheless` is even more formal and emphasizes that something happened *despite* the previous point.
