The traditional form 愛 contains: 爫 (a hand reaching or grasping at the top) + 心 xīn (heart, in the center) + 夂 zhǐ (a foot walking slowly at the bottom). A heart being carried forward by slow, deliberate steps — love as an act of movement, not a static state. The reaching hand above and the moving foot below frame the heart: love reaches toward its object and walks toward it.

The simplified form 爱 strips out the 心 heart radical entirely — a simplification that traditionalists often cite as culturally significant. 没有心的爱 (love without a heart) became a mild complaint in Taiwan and Hong Kong when simplified characters spread. Whether symbolic or merely practical, the absence of 心 is the most-noticed simplification in Chinese script reform.

In Confucian ethics, 爱 is central to the concept of 仁 rén (benevolence; humaneness) — the supreme virtue. Confucius described 仁 as 爱人 ài rén: "to love people." This is not romantic love but the orientation of care and concern toward all human beings, beginning with family and extending outward. The Mohist school challenged this by advocating 兼爱 jiān ài (universal love — equal love for all without gradation), which Confucians considered unrealistic. The debate between graduated love and universal love is one of the great questions of classical Chinese philosophy.
