How it's used

Focuses heavily on formal or legal contexts, such as the binding power of a document or the potency of a medicine. While it can describe the effectiveness of a product, it often sounds more serious or technical than simply saying 有用 or 有效. Use it when you need to emphasize the official status or the functional capacity of something to produce a specific result.

Common mistake

Do not confuse this with the adjective 有效, which means effective. Learners often try to use 效力 as an adjective, but it is strictly a noun that describes the power or validity behind an action or object.
