Etymology

Origin of pestilential

First recorded in 1350–1400; Middle English word from Medieval Latin word pestilentiālis. See pestilent, -ial

Explanation

Infectious, plague-causing, and definitely disease-bearing: If it's likely to bring along pestilence, then it's pestilential. Today we know that dirty hands, unclean water, and bubonic plague-carrying rats can all be potentially pestilential. But back in the olden days, the culprit wasn't so clear. Too much merriment, too little merriment, too much fresh air, too little fresh air — all were considered pestilential at one time or another.
