Etymology Information

'scalene' originates from Greek, specifically the word 'skalenos', where 'skalenos' meant 'uneven, unequal'.

'scalene' passed into Late Latin as 'scalenus' and later entered English (via New Latin/Scientific Latin and French influences) as 'scalene', used in geometry and anatomy.

Meaning Changes
