Grammar & Usage

fixed expression

How it works

This phrase describes something (an object, method, quality, etc.) that has demonstrated its capabilities or fulfilled its purpose completely. 充分 (chōngfèn) means 'fully' or 'adequately', modifying the verb 作用 (fāhuī zuòyòng - to play a role/function), which means 'to exert/give play to a role or effect'. The particle 了 (le) indicates the completion of the action.
