The kanji 惰 is a phono-semantic compound. It is composed of the semantic component 忄 (りっしんべん - "heart" or "mind"), which provides the meaning, and the phonetic component 余 (yo), which provides the sound. Together, they suggest a "heart" or "mind" that is "excess" or "left over," implying a lack of energy or motivation, leading to laziness. The "heart" radical directly relates to the character's meaning of a state of mind.
