-s ¹³ American  

1. an ending marking nouns as plural (boys; wolves ), occurring also on nouns that have no singular (dregs; entrails; pants; scissors ), or on nouns that have a singular with a different meaning (clothes; glasses; manners; thanks ). The pluralizing value of -s3 is weakened or lost in a number of nouns that now often take singular agreement, as the names of games (billiards; checkers; tiddlywinks ) and of diseases (measles; mumps; pox; rickets ); the latter use has been extended to create informal names for a variety of involuntary conditions, physical or mental (collywobbles; d.t.'s; giggles; hots; willies ). A parallel set of formations, where -s3 has no plural value, are adjectives denoting socially unacceptable or inconvenient states (bananas; bonkers; crackers; nuts; preggers; starkers ); cf. -ers.
