Upper-right portion — the inner strokes of
攸 (a vertical
丨 plus the
攵 hand-with-stick on the right), with the leftmost
亻 of standalone
攸 absorbed into the parent's own
亻 radical. Supplies the sound, with yōu shifting to xiū in
修 (a known palatal/sibilant alternation). Same phonetic series:
條 (slip/strip, simplified
条).
