屢次 is an adverb meaning 'repeatedly' or 'on several occasions'. It emphasizes that an action has happened multiple times, often with a sense of frequency that may imply expectation, frustration, or significance. The character 屢 means 'frequent' or 'repeated', while 次 means 'time' or 'occasion'—together, they literally convey 'many times'. It is commonly used in formal or written Chinese (e.g., reports, news, academic writing) and appears less frequently in casual speech, where words like 经常 or 总是 are more common.

This word carries a neutral-to-slightly-negative connotation depending on context—for example, it can highlight problematic repetition (e.g., repeated mistakes) or simply state factual recurrence (e.g., repeated visits). It typically modifies verbs and appears before the verb it modifies, often accompanied by aspect particles like 了 or 过. It does not function as a noun or adjective and cannot stand alone as a subject or object.
