-oma

See also: oma, Oma, OMA, omã, Omã, and omā

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)

1. (pathology) Forming nouns indicating disease or morbidity.
2. (pathology, specifically) Forming nouns indicating tumors or masses, which may be non-neoplastic or (more often) neoplastic, and (if the latter) either benign or cancerous (malignant); 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.
