Notes

1. もう expresses the idea that someone or something is not in the same state he or it was in some time ago. Thus, もう corresponds to 'already' or 'now' in affirmative declarative sentences, 'yet' or 'already' in affirmative interrogative sentences, and '(not) any more' or '(not) any longer' in negative sentences.

2. The opposite concept of もう is expressed by まだ.
