The others I was pretty much up on, although in all honesty, I only knew about decimate because I read THE ZOMBIE WARS. And although I realize it’s wrong, I still use less and disinterested incorrectly. I know. Shameful.
Language habits are funny. One misuse of a word can spread like a disease, one that’s highly contagious but not fatal. I don't think we have much to worry about because it takes quite a while for a word’s meaning to change even slightly. As those of you who actually read my etymology posts should know.
Are there any words you can’t help using incorrectly? Does it drive you crazy when someone says “I was so shocked my jaw literally hit the floor?” No? Just me then?
