Sometimes you see words used that seem to have been used pretentiously, or just downright incorrectly. Three such that really get my goat in some contexts are enormity, epoch and normalcy. Then you look them up and find that what bugs you can actually be perfectly correct. If I see "look at the enormity of that elephant," or "my childhood was an important epoch in my life," I emit growls. But investigation reveals that both those are correct. Well you may convince me that they're correct but you won't convince me that they're fine. And what's with the horrendous "normalcy?" It's not wrong but I simply never want to see it!
