Since I cannot verify the origin or formation of the kanji, I cannot explain the correspondence with other languages.

The kanji 故 is a phono-semantic compound (形声文字). It combines the phonetic component 古 (ko), meaning "old" or "past," with the radical 攵 (boku or nobun), which is a variant of 攴 and indicates "to tap" or "to strike," but also contributes to the meaning of "action" or "doing." Therefore, the character suggests an old or past event that has an effect or is the reason for something. This evolution makes the kanji often related to "reason" and "cause".
