'angular' originates from Latin, specifically the word 'angulus', where 'angulus' meant 'angle' or 'corner'.

'angular' entered English via Late Latin 'angularis' and Old French 'angulaire', and through Middle English it became the modern English word 'angular'.

Initially it meant 'of or relating to an angle'; over time it broadened to include 'having sharp corners', 'lean or bony (face)', and 'awkward in movement'.
