The kanji 顧 is a phono-semantic compound (形声文字, keisei moji). It combines the phonetic component 固 (ko), meaning "firm" or "solid," with the radical 頁 (おおがい), which means "head" or "page" and is used to represent concepts related to the head or thinking. The combination suggests the action of turning the head to look back firmly or reflectively. The phonetic component 固 provides the sound, and the radical 頁 contributes to the meaning, creating a character that signifies looking back or considering. The visual representation evokes the act of turning the head to look.
