‘无关’ is an adjective meaning 'irrelevant' or 'unrelated'. It combines two characters: 无 (wú), meaning 'without' or 'not having', and 关 (guān), meaning 'relation', 'connection', or 'concern'. Together, they literally mean 'without relation' — emphasizing a complete lack of connection or relevance between things. It is commonly used in formal or neutral contexts to dismiss something as having no bearing on the matter at hand.

This word frequently appears in written Chinese and spoken discourse when clarifying boundaries — for example, in explanations, arguments, or instructions where one wants to state that certain details, people, or factors do not affect the core issue. It often follows the structure '与...无关' ('has no relation to...') or stands alone after a noun or clause to indicate irrelevance. While it can be used predicatively (e.g., 这件事无关), it more commonly appears in attributive or complement positions, especially after 是 or 与.
