The kanji 患 is a 形声文字 (keisei moji), a phono-semantic compound character. It is composed of two parts: 串 (kan), which functions semantically indicating "penetrate" or "pierce". The other part is 心 (kokoro), meaning "heart" or "mind". Together, the character depicts a situation where "something pierces the heart," or that the heart is being invaded by something unpleasant, like illness or trouble. It evolved over time to represent the concept of suffering and affliction.
