1.  undergo the formation of pus; fester

Here’s why you should know and love this word: most obviously, it has to do with festering pus.  Which would be plenty enough reason to deploy the word liberally in your daily business communication.  But wait…there’s more.  Though officially the word is pronounced “supp-yer-ate,” people in the Midwest (and yrs. truly) pronounce it “super ate.”  Yes…just like the franchise of cheap and sleazy motels.  So the next time you’re driving along and hear a commercial inviting you to spend a night at the Super 8 Motel, you should, like me, cackle adolescently.
