You Could Look It Up
Q. For those who make a hobby of cruising garage sales, are they going “garage sale-ing,” “garage saling,” or “garage saleing?” Or are they not permitted this usage?
A. Oh, my. Is garage saleing anything like parasailing? The mind boggles. As you suspected, this phrase would not survive the red pencil at Chicago. (Why can’t you just go to garage sales?) I can tell you that suffixes like “ing” don’t normally take a hyphen. After that, you’re on your own.
