What I’m seeing all over the place, even on FR, is people neglecting to add an “s” to words ending in “ist” when they’re plural. I see sentences like, “We have to stop all those terrorist from coming in to the country.” “Those feminist are very angry.” Etc. Why has everyone suddenly decided that those words don’t need an “s” to be plural?
I blame computers for that one. I can't tell you how many times I've caught my computer dropping the s from the end of a word ending in 'ist'.
