What 忱 means
It means sincerity, heartfelt feeling, or trust.
Early examples in the Book of Songs and Book of Documents use 忱 for Heaven's trust and sincere conduct. As of 2026, the sources checked establish no single inventor or first inscription. Shuowen Jiezi analyzes it as 心 plus the sound element 冘, and later use centers on heartfelt feeling.
Is 忱 formal? Yes — alone it feels literary; compounds are its modern home.
Use 忱 in 热忱 and 谢忱; do not swap in 谌.
