But vs. However – Which is Correct?

Both but and however are correct English words that contrast ideas. Use but for the natural, concise conjunction within a sentence; use however as a conjunctive adverb to signal contrast, often after a period or semicolon. Although their meanings overlap, punctuation, position, and formality make them different in practice, slightly.

But or However – Which is Correct?

Both but and however are correct. They commonly introduce a contrast, concession, or qualification, but they do not function in exactly the same way.

But is usually a coordinating conjunction. It joins words, phrases, or two independent clauses in one sentence: The plan is affordable, but it may take longer.

However is usually a conjunctive adverb. It connects ideas across sentences or independent clauses and normally requires appropriate punctuation: The plan is affordable. However, it may take longer. It can also appear after a semicolon: The plan is affordable; however, it may take longer.

In general, but sounds more direct and conversational, while however often sounds more formal, deliberate, or emphatic.

The Best Trick to Remember the Difference

Use the sentence-joining test: if you want one short word to join two contrasting ideas inside the same sentence, choose but. If you want to begin a contrasting sentence or insert a formal transition, choose however.

Remember: but belongs inside the bridge; however often stands at the doorway of a new sentence. A comma alone cannot normally join two complete sentences with however. Write I was tired, but I continued, not I was tired, however I continued. The second version needs a period, semicolon, or a different construction.

Word	Part of Speech	Meaning	Example
but	Coordinating conjunction	Introduces a contrast or exception	The room is small, but it is comfortable.
however	Conjunctive adverb	Introduces a contrasting idea or qualification	The room is small. However, it is comfortable.

How to Use But

But is one of the most common contrast words in English. As a coordinating conjunction, it links elements that are grammatically equal, such as two adjectives, two phrases, or two independent clauses. It usually presents an idea that contrasts with or limits the statement before it.

When but joins two independent clauses, place a comma before it: The evidence was limited, but the conclusion was persuasive. When it joins shorter words or phrases, a comma is usually unnecessary: The solution is simple but effective.

But is suitable in casual conversation, general writing, academic prose, and professional communication. It is generally more concise and less formal-sounding than however.

Example 1: The forecast predicted rain, but the afternoon remained sunny.

Example 2: She wanted to attend but had another appointment.

Example 3: The instructions were lengthy, but they were easy to follow.

Etymology of the word But

But comes from Old English butan, meaning “outside,” “except,” or “unless.” Over time, its uses developed to include opposition and contrast. The modern conjunction reflects the word’s long-standing function of introducing an exception or qualification to a previous idea.

How to Use However

However is most commonly used as a conjunctive adverb meaning “nevertheless,” “in contrast,” or “despite that.” It connects a new statement to an earlier one while signaling that the new information differs from or limits what came before.

The same contrast between grammatical roles also appears when choosing While vs. Although in concessive clauses.

At the beginning of a sentence, however is typically followed by a comma: However, the results were inconclusive. In the middle of a sentence, it is often set off by commas: The results, however, were inconclusive. Between two independent clauses, use a semicolon before however and a comma after it: The method was promising; however, the results were inconclusive.

However is common in formal writing, reports, essays, journalism, and professional communication. It can sound more measured or sophisticated than but, although the two words are often interchangeable in meaning.

Example 1: The proposal appears practical. However, its costs require further review.

Example 2: The device is compact; however, it has limited storage capacity.

Example 3: The team, however, decided to continue despite the delay.

However can also mean “in whatever way” or “to whatever extent,” as in However you solve the problem, show your work and However carefully she planned, unexpected issues arose. In these sentences, it does not simply mean “but.”

Etymology of the word However

However developed from the combination of how and ever. Earlier forms expressed meanings such as “in whatever manner” or “by whatever means.” Its contrastive meaning, similar to “nevertheless,” emerged as the word became established as a formal connective in English.

Related Concepts

Understanding conjunctions, conjunctive adverbs, and sentence punctuation makes the difference between but and however much easier to apply accurately.

• Coordinating conjunctions: Words such as and, but, and or join grammatically equal elements. The coordinating conjunction but can connect two independent clauses when preceded by a comma.
• Conjunctive adverbs: Words such as however, therefore, and nevertheless show relationships between complete ideas. They do not normally join two independent clauses with only a comma.
• Independent clauses: An independent clause contains a subject and a verb and can stand alone as a sentence. Two independent clauses need suitable punctuation when combined.
• Contrast and concession: Both words can introduce information that conflicts with, limits, or qualifies an earlier statement.

Examples from Media and Literature

The following examples reflect common styles found in books, films, journalism, and everyday public communication. They illustrate how the two words work rather than reproduce copyrighted quotations.

• Novels: Narrative prose often uses but for a quick, natural turn in a character’s thoughts: He wanted to leave, but he stayed.
• Film dialogue: Spoken characters commonly choose but because it is brief and conversational: I understand your point, but I disagree.
• News reports: Journalistic writing frequently uses however to introduce a qualification: The policy received broad support. However, several groups raised concerns.
• Academic books: Formal analysis may place however within a sentence for emphasis: The theory is influential; its predictions, however, remain disputed.
• Public speeches: A speaker may use but for immediacy and however for a more formal transition, depending on the desired tone.
