Inflammatory disease.

Greek feminine form of adjectives ending in ‑itēs.

In Greek, such adjectives were often used alone, with a following noun understood, especially nosos, disease. For example, though nephritis in classical Greek strictly meant ‘of the kidneys’, it actually referred to a disease of that organ. Application specifically to inflammations occurred in English from the eighteenth century onwards. A large number of such terms now exists, of which a few are given in the list below.

The ending is often used facetiously in temporary formations that refer to some state of mind or tendency viewed as a disease: celebritis, excessive admiration for celebrities; electionitis; lotteryitis; millenniumitis.
