Etymology: "Bursitis" is built from "bursa," a Latin word for a purse or bag, and the suffix "-itis," which comes from the Greek "-itis," used to name inflammation. The Latin "bursa" itself had been borrowed from Greek "byrsa," meaning a hide or skin, which is why the sense of a pouch or sac came into the picture. Anatomists took "bursa" for the small fluid-filled sacs that cushion joints and tendons, since they looked like little purses. The suffix has a longer pedigree than the first half. In ancient Greek, "-itis" was used with words for body parts to name a diseased or inflamed condition, and Greek writers used it in medical contexts. Its ancestry runs back to an older Greek suffix that formed adjectives and nouns, but in English its job is simple: attach it to an anatomical noun and you get an inflammation. Hence "arthritis" for the joints, "tonsillitis" for the tonsils, and "bursitis" for the bursae. The combined word is a modern coinage. It was formed in New Latin, the scientific Latin used by early modern and later physicians, and English adopted it from there. Nothing in its making was ancient; the Greek and Latin parts were assembled by doctors to name a condition they had learned to recognise.
