Seems I'm guilty of misusing "comprise," also...learned a few things from this thread! I don't mind the mangulations (!) (ha) that result from a subpar education as much as I do the ones that are the result of being too lazy to look up the word in the dictionary! Expertise is one of those that gets mispronounced as ex-per-tees with an "s" sound on the end when it's supposed to be ex-per-teez with a "z" sound--like strip tease. A word I won't even use is forte (not the musical one, the other one) which is supposed to be pronounced as fort. But almost everyone insists on fort-ay. If I say it correctly, I'm corrected! lol

Speaking of medical ones, it really sets my teeth on edge to hear someone say, "I have a temperature." Duh. And lucky you are, to have one!
