In this case, the semantic component is "扌" (てへ - tehen), which is the "hand" radical, indicating an action done with the hand. The phonetic component is "弗" (futsu), which hints at the pronunciation. The original form depicts a hand giving away or removing something. Over time, it evolved to represent the actions of paying, brushing, or getting rid of.
