but

が – But; However (Clause Connector)

JLPT N5ConjunctionNeutral
placed at the end of a clause functions as a conjunction meaning "but" or "however," connecting two sentences into one. Unlike as a subject marker (が ①), this links two contrasting or related clauses, similar to けど or しかし. It sits at the boundary between the first clause and the second, typically after a verb, adjective, or copula in their polite (ます/です) or plain forms. Compared to けど, is slightly more formal and is very common in polite speech and writing. Compared to しかし and でも, which begin a new sentence, joins two clauses within a single sentence. An important nuance is that does not always express strong contrast; it is also used as a soft connector to introduce a topic or preface a request, functioning more like "and" or as a gentle lead-in rather than a sharp "but."

Functions

#1 Expressing contrast (but / however)

Structure
Clause 1 + が + Clause 2 (contrasting information)
日本語にほんごきです英語えいごはあまりきではありません。

I like Japanese, but I don't really like English.

Here connects two clauses that present contrasting information: liking Japanese versus not liking English. The speaker uses after the polite form です to smoothly transition to the second clause, which offers an opposing statement. This is the most common and straightforward use of as a conjunction, directly equivalent to "but" in English.

Common mistakes

Learners often confuse the conjunction (meaning "but") with the subject-marking particle . Context and position are key: the conjunction appears after a complete clause (after です, ます, or a plain-form predicate), while the subject particle appears after a noun. Another common mistake is using interchangeably with でも; remember that でも starts a new sentence, whereas connects two clauses within one sentence. Some learners also overuse for strong contrast where のに ("even though," with a sense of frustration or unexpectedness) would be more natural. Finally, beginners sometimes forget that can function as a soft lead-in without any real contrast, and they may misinterpret sentences like すみません as containing opposition when it is simply a polite preface.
