here is another thing that Julie and I have noticed to be on the increase.
sale is a noun. Sell is a verb.
for instance, I need to sell my trailer. (incidentally, it is a Big Tex 50LA. 16 feet, rails, hardly used. about two years old. I love my trailer and I love having a trailer, but I don’t use it enough to justify keeping it.)
or I could say that my trailer is for sale.
it is not correct to say that I need to sale my trailer.
nor is it correct to say that my trailer is for sell.
the former misusage is epidemic. everybody is trying to sale their houses and other stuff.
