Synonyms for But
Synonyms aren’t swappable parts. Each word has its own connotation, the feeling it adds beyond its dictionary meaning. Register means how formal or casual a word sounds. A collocation is a pair of words that often go together, like “nothing but.”
Sense 1: Contrast (most searched)
But is a conjunction, so it joins clauses. Some alternatives work the same way, and others are adverbs that need new punctuation. But and however belong to different word classes, so swapping them changes your punctuation.
| Word | How it differs | Example |
|---|---|---|
| yet (conj., neutral-formal) | A little more formal. It often hints at a surprise. | The room is small yet bright. |
| though (conj. or adv., informal-neutral) | At the end of a sentence it acts like a soft “but.” | The food was great. The service was slow, though. |
| although (conj., neutral) | Starts a clause, so you rebuild the sentence. | Although the room is small, it’s bright. |
| while (conj., neutral) | Sets two facts side by side. It also means “during,” so context matters. | Some students prefer notes, while others prefer videos. |
| whereas (conj., formal) | Compares two facts in a formal tone. | The first plan is cheap, whereas the second is fast. |
| however (adv., neutral-formal) | Needs a semicolon or period before it. | The room is small; however, it’s bright. |
| still (adv., neutral) | Warmer. It starts a new sentence. | The room is small. Still, I love it. |
| nevertheless (adv., formal) | The second point holds despite the first. “I like the plan; nevertheless, it costs too much” sounds odd. | The weather was cold; nevertheless, we hiked. |
| even so (adv. phrase, neutral) | The same idea in everyday words. | The hike was hard. Even so, we finished. |
Formality ladder. This ladder measures one thing: how formal the word sounds. The order is rough, because dictionaries don’t rank these words.
but → still → however → nevertheless
I left off yet, though, although, while, and whereas because their formality shifts with their place in the sentence. I also left off even so because it’s a phrase.
Related, not true synonyms: except that (adds an exception to a claim), only (an informal conjunction, as in “I’d go, only I’m busy”), and instead (replaces one thing with another).

- Jump to that sense and read the “How it differs” column.
- Check the register. Still suits blogs, and whereas suits reports.
- Check the grammar. However and nevertheless need a semicolon or period. Although needs a rebuilt sentence.
Antonyms for But
In the contrast sense, an antonym joins ideas that agree or follow. Each antonym is paired with the word it contrasts with. The “only” and “all but” senses have no true antonym.

|---|---|---|---|
| and (conj., neutral) | but, yet | Adds an idea that agrees. | The soup is hot and tasty. |
| so (conj., informal-neutral) | but | Shows a result. | It was late, so we left. |
| therefore (adv., formal-neutral) | however | Shows a result in a formal tone. | The road was closed; therefore, we took the bus. |
| including (prep., neutral) | except, apart from | Counts something in. | Everyone, including Sam, came. |
| in addition to (prep. phrase, neutral-formal) | except for | Adds, instead of excluding. | In addition to Maya, Dev came. |
| approval (noun, neutral) | objection | Agreement, not disagreement. | The plan won quick approval. |
Near-misses. Also adds an idea but doesn’t say whether it agrees. Because gives a reason, so it isn’t an opposite. Or offers a choice. In “not only X but also Y,” but adds an idea instead of contrasting, so and isn’t its opposite there. For more result words, see our antonyms for however.

Common Mistakes
Common mistakes box
- “Although… but.” “Although it’s cheap, but it’s slow” is a real error. Use one: Although it’s cheap, it’s slow or It’s cheap, but it’s slow.
- “But however.” It repeats the same job. Choose one.
- Mixing up all but and everyone but. All but finished means almost finished. Everyone but Sam means all except Sam.
- Pronoun case. In the “except” sense, but is a preposition, so many writers say “everyone but him.” Check your style guide.
- Never starting a sentence with but. Dictionary.com says but often begins sentences as a transitional word. Some teachers disagree, so check your style guide. dictionary
Repetition is a problem with many words. For another example, try synonyms for bad when “very bad” gets old.
