Literally: gut inflammation

The story of the word

That suffix is a grammatical accident that got promoted. In a phrase like arthrîtis nósos, disease of the joints, the ending was simply a feminine adjective agreeing with nósos; the noun fell away and the ending was left carrying the meaning alone, so nineteenth-century medicine could bolt -itis onto any organ it pleased. Énteron meant innards in general, which is why it also sits inside dysentery and gastroenterology.
