Etymology

Origin of rabies

First recorded in 1655–65; from Latin rabiēs “rage, madness,” from rab(ere) “to be mad, rave” + iēs, abstract noun suffix

Explanation

Rabies is a deadly disease that can be spread between mammals through saliva, usually when one animal is bitten by another. If you run into a raccoon foaming at the mouth, don't pet him; he may have rabies. Most dog and cat owners are familiar with rabies, because it's an illness they regularly have their pets vaccinated against. An unvaccinated pet that's bit by an animal with rabies almost always dies — and this is also true for humans who contract rabies and aren't treated. In Latin, rabies means "madness," and this accurately describes some of the symptoms of this terrible disease.
