Meaning
The kanji 悔 (HỐI) is a crucial character in Japanese, representing the deeply human emotions of regret, repentance, remorse, and lamentation. At its core, 悔 encapsulates the feeling of wishing one had acted differently, or a sense of sorrow over past actions or missed opportunities. It can also describe a state of being vexed, frustrated, or mortified by an unfortunate outcome.
Understanding the etymology of 悔 offers valuable insight into its meaning. This kanji is classified as a phono-semantic compound (形声文字, keisei moji). This means it combines a semantic component, which suggests its general meaning, with a phonetic component that hints at its pronunciation.
The semantic component is 心 (kokoro), the radical for 'heart' or 'mind', which clearly signifies that this kanji deals with emotions, feelings, and internal states. The phonetic component is 毎 (mai), meaning 'every' or 'always', which also contributes to the on'yomi 'カイ' (kai). The combination of 'heart' (心) and 'every/always' (毎) can be interpreted as a heart that constantly or repeatedly feels a certain emotion, specifically regret or remorse. This visual connection highlights a persistent, often gnawing, emotional state rather than a fleeting one. The feelings associated with 悔 are often deep-seated and can linger for a significant period.
Comprising 9 strokes, 悔 is a Jōyō Kanji (常用漢字), one of the 2,136 characters designated for general use. While not taught in elementary school, it is typically learned in junior high or high school. This makes it essential for advanced Japanese literacy, consistent with its N1 JLPT level.

Memory Tip
To easily remember 悔, focus on its two key components. The bottom part, 心 (kokoro), means 'heart' or 'mind', immediately signaling that this kanji relates to emotions and internal states.
The top part is 毎 (mai), meaning 'every' or 'always'. Imagine combining 'heart' with 'every' or 'always' to visualize a heart that constantly feels something—specifically, a recurring sense of regret or remorse. Picture your heart persistently nagging you about a past mistake, or always returning to that feeling of frustration. This continuous emotional state is the essence of 悔. So, a 'heart' (心) that 'every' (毎) now and then feels a pang of sorrow or vexation leads to 'regret' or 'repentance'.
