40 Useful Synonyms for But to Show Contrast Clearly

But is a coordinating conjunction that introduces a contrast or exception to what was just said. Because it’s a function word rather than a content word, its useful alternatives are tied to specific grammatical roles: some work as conjunctions joining two clauses, others as adverbs starting a new sentence, and others as subordinating conjunctions that restructure the sentence entirely.

However and yet both signal contrast the way but does, though however typically starts a new sentence or follows a semicolon, while yet can slot directly into the same spot as but. Although and while restructure the sentence differently, turning one half into a subordinate clause rather than joining two equal statements.

This guide sorts alternatives to but by their grammatical role, so you can swap it out correctly rather than just approximately.

What Does But Mean?

Part of speech: Coordinating conjunction (also used as a preposition meaning “except”).

Only — informal, introduces a contrasting condition. Example: “I’d love to help, only I’m swamped this week.”

Alternatives That Start a New Sentence

However — the most common formal alternative, typically starting a new sentence or following a semicolon. Example: “The results were promising. However, more research is needed.”
Nevertheless — stronger and more formal, emphasizing contrast despite something. Example: “The odds were against them. Nevertheless, they succeeded.”

Still — informal, common in everyday speech. Example: “It’s expensive. Still, it might be worth it.”

Conversely — formal, often used when contrasting two opposing facts or ideas. Example: “Sales rose in the city. Conversely, rural sales declined.”
On the contrary — stronger, often used to directly correct or oppose a previous statement. Example: “It wasn’t a failure. On the contrary, it exceeded expectations.”

Alternatives That Restructure the Sentence (Subordinating Conjunctions)

Though — similar to although, slightly more casual. Example: “Though tired, she finished the report.”
Whereas — formal, often contrasting two parallel facts. Example: “Whereas the first draft was rushed, the second was carefully edited.”

But vs Similar Words

But vs However

Both signal contrast, but “however” typically starts a new sentence or follows a semicolon, while “but” joins two clauses directly within the same sentence. Using “however” the way you’d use “but” mid-sentence usually creates a grammatical error.

But vs Although

Although restructures the sentence, turning one part into a subordinate clause: “Although it was late, we kept working” versus “It was late, but we kept working.” Both convey similar meaning through different grammatical structures.

But vs Yet

These are nearly interchangeable in most contexts, though “yet” can feel slightly more literary or emphatic. “She apologized, but he still wasn’t happy” and “She apologized, yet he still wasn’t happy” work almost identically.

How to Choose the Right Alternative to But

Start by checking whether you want to join two clauses in one sentence or start a new sentence entirely.

To join two clauses directly, “yet” works as a close substitute for but. Example: “The trip was long, yet it was worth every minute.”

To start a new sentence, “however” is the standard formal choice. Example: “The trip was long. However, it was worth every minute.”

To restructure the sentence with a subordinate clause, “although” or “though” work well. Example: “Although the trip was long, it was worth every minute.”

Common Mistakes When Replacing But

Using “however” mid-sentence the way “but” is used. This often creates a run-on or comma-splice error; “however” usually needs its own sentence or a semicolon before it.
Confusing “although” with “but” grammatically. Although requires restructuring the sentence into a subordinate clause, not simply swapping the word.
Using “so” or “because” as if they mean the same as but. Both signal cause or result, not contrast.
