All negations don’t sound right to me.
I’m accustomed to hearing people make grammatical mistakes, but occassionally I’ll start hearing new and painful trends that are so pervasive that I wonder if someone changed the rules while I was asleep. Case in point: how to negate constructions containing the words “all” or “some”. A few months ago, I was looking at some magazines at the grocery store and saw an ad asserting that “all insurance policies are not the same”. I’ve been hearing that kind of construction from high school kids for some time, but always attributed it to poor language skills. A few minutes later, I went to use the store’s bathroom and saw the following sign on the door: “All unpaid merchandise not allowed in restrooms”. Now those of you who grew up in the America that I grew up in know that prior to the George H.W. Bush administration, such locutions would have read “Not all insurance policies are the same” and “No unpaid merchandise allowed in restrooms”. What has happened here? I now hear this “all...not” construction constantly and I’m not sure what to make of it. When I hear a teacher lament, “All of my 8th-graders didn’t finish their chapter test on time.”, what does she mean to communicate by that? Does she mean to say that NOT ONE of them finished (supported by literal deconstruction)...or that some did and some didn’t (supported by a higher likelihood of being the case)?
