Morphology

adenoma = aden + oma

Composed of Greek combining forms ('aden-' for gland and the medical suffix '-oma' for tumour) that are unlikely to be recognizable to an average B1 learner, so the meaning is not derivable from familiar English base words.

Etymology

The word adenoma comes from Greek parts: aden- meaning 'gland' and -oma meaning 'swelling' or 'tumor'. So an adenoma is a 'gland' swelling, a growth from gland tissue that is usually not cancerous.
