The kanji 冴 is a phono-semantic compound (形声文字). The left side is the radical 冫 (ni), which signifies "ice" or "cold." The right side is 牙 (ga) which is "tooth" or "fang". This combination suggests something sharp, clear, and cold. The "ice" element is believed to have been added later, and it might have been used to indicate coldness or clarity associated with sharp objects.
