The kanji 凪 is a phono-semantic compound (形声文字 - keisei moji). It combines the radical 風 (kaze - wind) on the left side, which provides the meaning of wind, and the phonetic 止 (shi - stop, halt) on the right side, which provides the sound and hints at the meaning of stillness. Essentially, it depicts "wind" that has "stopped," thus creating the meaning of a calm or still environment.
