The kanji 怠 is a phono-semantic compound. The left side is the radical 忄 (りっしんべん, "heart" or "mind"), indicating that the meaning is related to a mental or emotional state. The right side is a phonetic component, 㞢, which gives a clue about the pronunciation. Thus, the kanji 怠 combines the "heart" element with a sound element to represent the idea of a lazy or idle mind or lack of motivation. The original shape of 㞢 is related to the meaning of "relax" or "ease", which contributes to the meaning of idleness.
