Usage Notes

完善 is both a verb and an adjective. As a verb, it means "to improve/perfect" something that is already partially good but needs refinement. It implies incremental improvement rather than complete overhaul. It is especially common in government, policy, and institutional contexts.

As an adjective, 完善 describes something as comprehensive and fully developed (完善的体系 -- a well-developed system). Note that 完善 implies a high standard but with room for ongoing improvement, unlike 完美 (perfect, flawless) which implies no room for improvement.

Memory Hook

完 (complete) + 善 (good/virtuous) -- making something completely good is what it means to 完善 it.
