The kanji 挑 is a 形声文字 (keisei moji), a phono-semantic compound character. It combines two parts: the radical 扌(てへん) (tehen), meaning "hand" or "action", and the phonetic component 兆 (chou, meaning "omen", "sign" and also phonetically contributing the sound). The "hand" radical suggests the action of "doing," and the phonetic part 兆 provides the sound and hints at the idea of something initiating or starting, thus linking to the sense of "challenging" or initiating an action.
