The kanji 妨 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is the radical 女 (じょ, onna), meaning "woman," and the right side is 方 (ほう, hou), which conveys the sound and meaning of "direction" or "square." Originally, it might have suggested a woman standing in the way or obstructing something. The 方 acts as a phonetic component, giving the kanji its sound (bou). Over time, the meaning shifted to a broader sense of obstruction and hindrance, not limited to women.
