The kanji 救 is a phono-semantic compound (形声文字). It is composed of two parts: the radical 求（kyuu, meaning "to seek" or "to request"）and the sound component 又（yuu, meaning "again" or "hand"). 求provides the semantic (meaning) element, conveying the idea of seeking or requesting help, while 又contributes to the pronunciation and provides the meaning that hand is required. Therefore, the character's formation suggests seeking or requesting help, often with the hand, to rescue someone from danger or provide aid. The character's historical development reflects its central meaning of assistance.
