Definition
瞬时 is an attribute word (区别词) that means 'instantaneous' or 'in an instant.' It directly modifies a noun to describe something that happens or exists for an extremely short moment and cannot serve as a predicate (e.g., 瞬时速度 'instantaneous velocity' is correct, but *速度很瞬时 is not). You'll encounter it in formal or technical contexts such as physics, engineering, or description of rapid events.
