‘倾心’ literally means 'to倾 (tilt, devote) one’s 心 (heart)' — suggesting a complete emotional surrender or deep, heartfelt commitment. It conveys strong affection, romantic attraction, or profound admiration, often implying that the person has given their full emotional attention and devotion to someone or something.

This word is commonly used in literary, poetic, or formal contexts — especially when describing falling in love, being captivated by a person’s character or talent, or developing deep passion for an art form or cause. While it can appear in modern spoken Chinese, it carries a slightly elevated or refined tone and is rarely used in casual daily conversation among young people. It emphasizes sincerity and intensity of feeling rather than fleeting infatuation.
