Etymology

Origin of inflammation

First recorded in 1525–35; from Latin inflammātiōn-, stem of inflammātiō, from inflammāt(us) “kindled” (past participle of inflammāre “to kindle”; see inflame) + -iō -ion

Explanation

An inflammation means "setting something on fire." Maybe it's a political movement that suddenly takes hold, romantic feelings, the heat making your shoes feel tight, or someone lighting a campfire. Inflammation comes from the root inflame, from the Latin word inflammare meaning "to set on fire with passion." That meaning sounds pretty good, but an inflammation on your face, like a terrible rash, probably isn't going to inflame anyone's passion, at least until the swelling goes down. It probably also causes pain and discomfort.
