Standard Deviants School - English Grammar, Program 5 - Agreeing with Grammar (Classroom Edition)
The Standard Deviants discuss how a word that usually works as one part of speech can put on a disguise and pretend to be another part of speech, including nouns as verbs, and verbs as nouns. Then it's time to tackle proper agreement in grammar, including subject/verb agreement and proper agreement between nouns and articles.
