但是 vs 然而 (dànshì vs rán'ér): which 'but' to use

但是 (dànshì) is the neutral, default adversative conjunction meaning 'but' for both spoken and written Chinese. 然而 (rán'ér) is a formal, literary 'however' typically used in written discourse to introduce a strong contrast. Choose 但是 for everyday speech and general writing; reserve 然而 for formal essays, academic texts, or rhetorical emphasis.

Both 但是 and 然而 mean 'but' or 'however', indicating a contrast or exception. 但是 is the neutral, most common choice in spoken and written language, suitable for nearly any situation. 然而 is more formal and literary, typically used in written Chinese to introduce a strong or unexpected contrast, often at the beginning of a sentence or independent clause. The core mental model: use 但是 for general purposes; use 然而 in formal writing or when a more emphatic, rhetorical contrast is desired.

When to use each

但是dàn shì

but

Use 但是 as the default adversative conjunction in both speech and writing. It connects two contrasting clauses or sentences in a neutral tone. It is appropriate in casual conversation, emails, essays, and most contexts.

但是 can be softened with 不过 (bùguò, 'but') for a milder contrast, or strengthened with 可是 (kěshì) for emphasis in spoken Chinese.

然而rán ér

however (formal)

Use 然而 in formal or literary writing to introduce a strong or unexpected contrast. It often starts a new sentence or independent clause. Common in academic papers, official documents, speeches, and classical Chinese-style writing.

然而 is more emphatic than 但是; it can imply a concession followed by a stronger opposing point. In modern usage, it is rarely used in speech without sounding overly formal.
