～上手

About

上手じょうず is a な-adjective/noun that can be used to describe one's abilities. Usually, 上手じょうず is translated as "good at", or "skilled with".

We can use the が particle to attach 上手じょうず to nouns, or nominalized verbs. (It is also possible for 上手じょうず to follow は or other parts of speech, depending on the context.)

上手じょうず should generally be avoided when talking about one's own abilities, as it sounds overly braggy.

You can negate 上手じょうず using じゃない or ではない to express "not good at". This structure can be used about oneself without sounding braggy.
