If you enjoy words and word usage, it is your blog! Lori, Guido, and I may be the ones posting, but we share a love of language and have a mutual interest in a continued effort to improve and learn, and have some fun along the way.
My topic today is reflected in the title of this entry: who's vs. whose.
Who's is a contraction of who is or who has. An appropriate use would be "Who's got the football?" or "Who's going with me to the football game?"
Whose is the possessive of who, and is used to show...well, possession. "Whose football is this?" or "Whose house are we watching the football game at?" (You could also say "At whose house are we watching the football game?" but that sounds a little stilted.)
As with other contractions, a good way to remember which is correct is to expand the contraction. In the first case, "Who has got the football?" makes sense. In the second case, "Who is football is this?" makes no sense whatsoever.
As for the score...who's counting?
