撇 = hand 扌 + 敝 (worn-out rag); your hand flings the worn thing aside
The 扌 hand radical marks an arm action, and 敝 means worn-out or ragged. Together: the hand casts away the tattered thing. 撇 is also the name of the left-falling stroke in characters, which sweeps away to the lower left.
撇 — hand radical 扌 + 敝 (worn/tattered)
A semantic-phonetic compound: 扌 (hand) gives the meaning of a hand action, while 敝 supplies the sound. Originally meant to brush, wipe, or fling away with the hand, which extended to discarding and to the leftward sweeping brushstroke in calligraphy.
