The kanji 啓 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is 戶 (to), meaning "door" or "household," which provides a semantic element. The right side is 㓞 (kei or ketsu), which provides the phonetic element. Together, they suggest "to open a door" or "to begin something." The 户 (to) implies the starting or opening. The 㓞 (kei/ketsu), in this case, provides the sound, as well as the sense of "sharpness" or the initial cut or incision.
