～といい

About

The ～といい pattern can be used to express the speaker's hopes/desires for either themselves or for the listener, and is often translated as "It would be nice if X," or "I hope X".

～といい can directly attach to a verb/い-adjective, or to nouns/な-adjectives using だ.

E.g. 明日あした、晴はれるといいね。 "I hope it's sunny tomorrow."

E.g. キャンプ場じょうがきれいだといいな。 "I hope the campground is nice."

～といい is very often combined with けど or other conjunctions to form the "It would be nice if X, but Y" pattern.
