The kanji 惇 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is the radical 忄 (りっしんべん, risshinben), which signifies "heart" or "mind," indicating that it relates to feelings, character, and mental states. The right side is 屯 (ton), which is the phonetic component, contributing to the sound ジュン (jun). The combination of the "heart" radical and the sound component suggests "a heart that is full and overflowing," thus leading to the meanings of sincerity, kindness, and generosity.
