ameloblastoma singular

Morphology

ameloblastoma = ameloblast (opaque) = ameloblast + oma

The formation 'ameloblast' + '-oma' follows a regular medical suffixation pattern meaning 'tumor of X', but both the base and the suffix are technical and not familiar to general learners.

Etymology

The word ameloblastoma comes from three parts: amel- meaning 'enamel', blast- meaning 'young cell', and -oma meaning 'tumor', as in melanoma. So an ameloblastoma is a tumor made from the young cells that make tooth enamel, which explains why it appears in the jaw or gum.
