The kanji 任 is a phono-semantic compound (形声文字; keisei moji). It combines the 人 (person; human) radical on the left side with the 壬 (nin, a zodiac sign; to bear; to carry) on the right side which functions phonetically. The right side contributes the sound and possibly the meaning of “to carry” or “to bear.” The left side, 人 (person), indicates the subject or agent involved. The original meaning likely related to entrusting or assigning a person to a responsibility. Over time, the character evolved to encompass ideas of responsibility, appointment, and duty.
