The kanji 悪 is a 形声文字 (keisei moji), a phonetic-semantic compound. It combines two elements: ⚫︎ The top part is 亜 (a), which originally depicted a type of building or shelter, but its semantic meaning here is secondary. ⚫︎ The bottom part is 心 (kokoro), meaning "heart" or "mind." The combination suggests something that affects the mind or heart in a negative way, thus conveying the meaning of "bad" or "evil." The 亜 (a) part contributes the sound (phonetic element) and a subtle suggestion of something confined or constrained, reflecting the restricting nature of evil or badness.
