Definition
一动 is a noun meaning 'a single movement' or 'a jolt', but it's most commonly used in the pattern 一动就... (yī dòng jiù...), meaning 'as soon as (someone) moves, (something happens)' — often implying a cause-effect relationship where even a slight motion triggers a result. It can also appear in the colloquial adverb sense 'at every turn' or 'easily', as in 动不动 (dòng bu dòng) 'at the drop of a hat'. The word is primarily a noun in HSK 7, but its usage extends into adverbial patterns.
