Ài mù is a verb meaning 'to be romantically attracted to' or 'to admire someone with romantic interest.' It combines 爱 (ài), meaning 'love' or 'to love,' and 慕 (mù), meaning 'to admire' or 'to yearn for.' Together, they express a gentle, often respectful, romantic admiration — stronger than casual liking but usually less intense or committed than deep love (爱情). It frequently appears in literary, poetic, or formal contexts, describing the early or unspoken stage of romance.

This word emphasizes emotional resonance and idealization rather than physical desire or long-term commitment. It’s commonly used to describe feelings toward someone admired for their character, talent, or appearance — for example, a student admiring a teacher, or someone quietly drawn to a colleague. Unlike 恋爱 (liàn’ài, 'to date'), ài mù does not imply mutual involvement or active courtship; it may remain one-sided or unexpressed.
