Translation guide
The English word "sober" has two main meanings: not drunk, and serious/calm. This guide covers both, with natural Japanese expressions for each.
Describing a state of not being under the influence of alcohol, or returning to that state.
The most common and natural word for 'sober' (not drunk). Can be used as a noun or na-adjective.
Describing a person, attitude, or atmosphere that is serious, solemn, or not playful.
Means serious, earnest, or sober-minded. Often used for a person's character or attitude.
しらふ only means 'not drunk'. It cannot be used to describe a serious personality or atmosphere. Use 真面目 or 落ち着いた instead.
