- humerus (n.)
- 1706, "bone of the upper arm," originally (14c.) "shoulder," from Latin humerus, a common spelling of umerus "shoulder," from PIE *om(e)so- "shoulder" (cognates: Sanskrit amsah, Greek omos, Old Norse ass, Gothic ams "shoulder"). Blount's "Glossographia" (1656) has humerous (adj.) "That hath great shoulders."
