Stomatitis

/ˌstoʊməˈtaɪtɪs/noun

Inflammation of the lining of the mouth, from infection, injury, deficiency or treatment.

The Greek roots

στόμα
stóma
mouth, opening
+
-ῖτις
-îtis
inflammation of

Literally: mouth inflammation

The story of the word

The -itis ending began as an adjective agreeing with νόσος, disease, so arthritis started life as "arthritic [disease]" and then swallowed its own noun. στόμα names the mouth of a river and the edge of a blade as readily as the mouth of an animal, which is why a surgical stoma is any created opening. Clinicians keep it separate from gingivitis, which stops at the gums.
