Morphology

deltoid = delta (transparent) = delto + oid

Formed from the combining form delto- (delta) + the productive suffix '-oid' meaning 'like' or 'resembling', so the sense 'triangular-shaped' is directly predictable.

Etymology

Deltoid comes from the Greek letter delta, which means 'triangle', and the ending -oid which means 'like'. So a deltoid shape is simply 'triangle-like', often with a point at the top.
