Morphology

arteriole = artery (semi-transparent) = arterio + ole

The meaning 'small artery' is straightforward, but the word uses the combining form 'arterio-' and the diminutive suffix '-ole', which may be unfamiliar in form to average learners.

Etymology

Arteriole comes from artery plus the ending -ole, which means 'small'. So an arteriole is a 'small artery' that leads into capillaries.
