未能

未能 is an adverb meaning 'failed to' or 'was not able to.' It expresses the inability to accomplish something, often implying a negative outcome or unfulfilled expectation.

The character 未 (wèi) means 'not yet' or 'un-,' and 能 (néng) means 'to be able to' or 'can.' Together, 未能 conveys the idea of not having succeeded in doing something despite the intention or effort.

It is commonly used in formal and written contexts, such as news reports, academic writing, or official documents. 未能 often appears in sentences describing missed opportunities, unsuccessful attempts, or unmet goals. It is similar to the English phrases 'did not manage to' or 'was unable to.'
