Morphology

backside = back + side (transparent) = back + side

A clear compound referring to the rear part of the body; learners can derive 'buttocks' from 'back' + 'side'.

Etymology

Backside also names the part of the body you sit on. It is the 'back' side of your body, which is why it means 'buttocks'.
