摯

A phono-semantic compound consisting of:

手 (hand) — semantic component, indicating physical action;

執 (to hold; jí) — phonetic component, providing the sound. The structure conveys firmly holding something with the hand, which later extended metaphorically to holding firmly in one’s heart to sincerity.
Semantic development: - to grasp firmly with the hand; - to hold tightly; - to hold emotionally or mentally; - deep sincerity; earnest feeling. Thus, 摯 evolved from physical holding to emotional depth and sincerity.

In Korean, 摯 appears mainly in formal or literary expressions, especially related to deep emotion or relationships.

진지 (眞摯) — sincerity; earnestness

지우 (摯友) — close friend

Frequently used in expressions describing deep relationships or genuine emotion.

Compared to 誠, which is general sincerity, 摯 suggests warm, heartfelt, and deeply personal sincerity.
