Morphology

pilomotor = motor (opaque) = pilo + motor + pilo

Although analyzable as 'pilo-' (hair) + 'motor' (mover), 'pilo-' is a rare technical combining form and the term is specialized, so average learners cannot reliably infer the meaning.

Etymology

Pilomotor comes from two parts: pilo- meaning 'hair' and motor meaning 'mover', like the machine motor that makes things move. So a pilomotor reaction is literally a 'hair mover', which explains goosebumps when your hair stands up.
