The -P Convention

Turning a word into a question by appending the syllable ‘P’; from the LISP convention of appending the letter ‘P’ to denote a predicate (a boolean-valued function). The question should expect a yes/no answer, though it needn't. (See T and NIL.)

At dinnertime:
      Q: Foodp?
      A: Yeah, I'm pretty hungry. or T!

At any time:
      Q: State-of-the-world-P?
      A: (Straight) I'm about to go home.
      A: (Humorous) Yes, the world has a state.

On the phone to Florida:
      Q: State-p Florida?
      A: Been reading JARGON.TXT again, eh?
