Surface Forms

nucleole singular
nucleoles plural

Morphology

nucleole = nucleus (semi-transparent) = nucleus + ole

Formed from 'nucleus' with the diminutive element '-ole' meaning 'small', but the diminutive is Latin-derived and not a productive, fully transparent English suffix for many learners.

Etymology

Nucleole comes from nucleus meaning 'core' or 'kernel' and the small ending -ole meaning 'little'. So a nucleole is literally a 'little nucleus' inside the cell's nucleus, which fits because it is a small round part that helps make the pieces the cell uses to build proteins.
