The kanji 排 is a phono-semantic compound (形声文字). The left side is a radical called 手 (te - hand) and the right side is 非 (hi - not). The 手 radical represents action or the hand, and the 非 is a phonetic component, adding meaning of "not." Therefore the whole character is to use the hand to get rid of something, exclude something, push something away, or arrange it.
