Morphology

psammoma = psammo + oma

Although analyzable as the combining form 'psammo-' (sand) + the medical suffix '-oma' (tumour), these are specialized medical forms not recoverable for an average B1 learner.

Etymology

Psammoma comes from the Greek word psammos meaning 'sand' and the ending -oma meaning 'tumor', the same -oma you see in melanoma. So a psammoma is a tumor that often contains many 'sand-like' hard particles, which is why it has this name.
