Notice to dumbasses of the world!
These are two of the most commonly misunderstood words in the English language; they're even used incorrectly in trade publications — by "professional" writers and editors, as well as on signage. The difference is very simple, so there should be no confusion.
premise – A proposition upon which an argument is based or from which a conclusion is drawn.
premises – 1. Land and the buildings on it.
2. A building or part of a building.
The word "premises" is not a plural for "premise." Get over it…get with the program! Smarten-up your language skills — editors and everybody else!
