# -oma
## English
### Etymology

From Ancient Greek -ωμα (-ōma), from verbs in -όω (-óō) + -μα (-ma) (from Proto-Indo-European *-mn̥), which lengthens a preceding vowel.

### Suffix

-oma (plural -omata or -omas)
* (pathology) Forming nouns indicating disease or morbidity.
* (pathology, specifically) Forming nouns indicating tumors or masses, which may be non-neoplastic or (more often) neoplastic, and (if the latter) either benign or malignant (cancerous); in accord with present-day understanding of histopathology, the suffix is now nonproductive for non-neoplastic senses.
    Synonyms: -cele, -coele

#### Usage notes

* For most nouns formed with -oma, the plural in -omas is more common, because the suffix has been naturalized into English, but the plural in -omata is often preferred by people who believe that the Greek inflection needs to be retained.
