In oracle-bone inscriptions, the graph 厷 depicts a bent upper arm.
Tips
history
厷 is the older form whose original meaning was 'upper arm' - the oracle-bone graph showed a bent arm with the elbow flexed. Later writers added the flesh radical ⺼ to clarify the anatomical sense, giving the modern character 肱. The famous classical pair 股肱 ('thighs and arms' → trusted ministers) preserves the underlying body-part imagery.
register
Archaic - definitions follow classical attestation only. Modern Chinese always writes 肱 for the arm sense and 宏 for the 'vast' sense. You encounter 厷 only as a component element (it's the right side of 雄 'male' and 弘 'expand') or in transcribed oracle-bone studies.

upper arm
Pictograph of a bent upper arm with a small marker indicating the bicep / elbow joint. Indexed under Kangxi #28 厶 (the curl) by tradition; the radical isn't transparently semantic in the modern form. Lives on as the right component of 弘, 雄, and as the inner phonetic of 肱.
Filed under radical 厶 (sī, #28) by convention. 厶 is not a separate component in 厷, so no strokes are highlighted.
