But I have my bugaboos. So does Ben Yagoda over at Slate.
Yes, I know that language changes over time and some things that we consider perfectly acceptable would have left folks in prior centuries aghast. My main concern is the same as Yagoda's, the few words for which we have no proper substitute.
"Literally", of course, is the granddaddy of them. To me, anyway. Yagoda avoids its discussion. Maybe it's too obvious. Or too painful.
As Yagoda points out when discussing "disinterested", there is no exact synonym for that word. (Oddly enough, in a prior paragraph, he points out that "impartial" means roughly the same thing.) But this is even more true for "literally". Please try to name a synonym for it. Once it loses its meaning, we have no single word left to express this concept. This is where language's evolution becomes devolution.
