What it means
うちに expresses doing something while a situation or condition still lasts, or before it changes. It can mean “while,” “during,” or “before it is too late.” With verbs, it often highlights taking action before a condition changes, especially with a negative form such as ないうちに. With ているうちに, it can describe a gradual or unexpected change that occurs as an activity continues.
Usage note
うちに is not interchangeable with 前に in every context. うちに emphasizes that the current state is still continuing or that a change may occur, while 前に simply means “before.” For a deadline or a clear sequence of events, 前に may sound more direct.
