んだけど

But..., And...

Structure

Phrase (A) + のだ⁽¹⁾ + が⁽²⁾ + Phrase (B)

⁽¹⁾ んだ
⁽²⁾ けれども、けれど、けども、けど

Explanation

The phrase んだけど joins んだ, used for providing context or a reason, with けど, meaning 'but'. While it often translates to just 'but...', its underlying nuance is 'given this situation (A)... (B)'. The second part of the sentence, (B), is frequently omitted. This suggests the speaker is inviting a response, or is hesitant to state the second part directly due to politeness or social awkwardness.

一緒(いっしょ)に映画(えいが)を見(み)に行(い)きたいんだけど、今日(きょう)は宿題(しゅくだい)がたくさんあるんだ。
I'd like to go see a movie with you, but I have a lot of homework today.
週末(しゅうまつ)に友達(ともだち)とバーベキューをするのですが、山田(やまだ)さんも来(き)ませんか？

日本(にほん)へ旅行(りょこう)したいのだけど...どんな服(ふく)を持(も)っていけばいいか分(わ)からない。

This grammatical structure has a few variations that can generally be used in place of one another. They are listed below, ordered from most informal to most formal:

んだけど、んだけれど、んだけれども、んだが、んですが

In any of the forms above, ん can be substituted with の. Using の makes the expression a little more formal.

Caution

Among these options, んだが (or just だが) carries the most assertive nuance and is typically perceived as masculine. When using this form, it's advisable to soften your tone to avoid sounding overly forceful or demanding.

Fun Fact

It is grammatically possible to omit the ん (or の) entirely, although this is not very common in contemporary Japanese.
