I have to admit, I don't see anything wrong with "10 items or less". Maybe I'm growing stupid. (Guessing: "ten"? "fewer"?)
dwmw2's frustration with misuse of language mirrors my own. Among apostrophe abuses, my favorite is faking an acute accent that should be over the preceeding letter. This is especially common here in the southern US. "cafe'" Some people even name their children using it. Ha!
Currently, my biggest language irritation is the recent surge in use of "I" outside of the subject of sentences. I think it bugs me because it's not a normal ignorance-of-the-language problem; one has to go out of one's way to use "I" incorrectly.
[I first posted "Currently, by bigest language irritation". :\ I blame my new split keyboard. :) Though, it has proven to me that I type incorrectly, especially in hitting 'y' with my left forefinger, which is no longer possible.]
Dear Mister Language Person: What is the purpose of the apostrophe? Answer: The apostrophe is used mainly in hand-lettered small business signs to alert the reader than an "S" is coming up at the end of a word, as in: WE DO NOT EXCEPT PERSONAL CHECK'S, or: NOT RESPONSIBLE FOR ANY ITEM'S. Another important grammar concept to bear in mind when creating hand- lettered small-business signs is that you should put quotation marks around random words for decoration, as in "TRY" OUR HOT DOG'S, or even TRY "OUR" HOT DOG'S.
