Etymology

Origin of rabid

First recorded in 1605–15; from Latin rabidus “raving, furious, mad,” from rab(ere) “to rave, be mad” + -idus -id 4

Explanation

Chances are that if the tail-wagging dog that just appeared on your doorstep is also foaming at the mouth and chewing on your welcome mat, it's rabid and you should back away slowly; no petting for this infectious pup. While you've likely heard it used to describe an animal infected by rabies, rabid (derived from the Latin verb rabere, "be mad, rave") can also dramatically describe a person exhibiting fanatical, extremely enthusiastic, or raging behavior. That guy who nearly knocked you off the stands at the football game with his energetic fist-pumping and then was later kicked out for getting into a fight with another fan? Rabid on both counts.
