Morphology

spindle = spin (transparent) = spin + dle

A rotating shaft is readily interpretable as a part that 'spins', a straightforward derivation from 'spin' with '-dle'.

Etymology

Spindle comes from an old word related to spin, which means 'to turn'. A machine spindle is the shaft that turns and holds parts, so the word shows it is the part that 'spins' in the machine.
