Morphology

spindle = spin (semi-transparent) = spin + dle

The biological structure is named by resemblance to the slender instrument or shape of a spindle, a metaphorical extension not directly inferable from 'spin' by many learners.

Etymology

Spindle comes from an old word related to spin, which means 'to turn' or 'twist'. In biology, the spindle is a group of fibers that acts like tiny ropes and a turning axis to pull chromosomes apart, so the name links to its job of moving and arranging parts.
