-oma

From Ancient Greek -μα (-ma).

-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 benign or cancerous (malignant).

• 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.
