Anthimeria

In rhetoric, anthimeria, traditionally and more properly called antimeria (from the Greek:ἀντί, antí, "against, opposite" and μέρος, méros, "part"), involves using one part of speech as another part of speech, such as using a noun as if it were a verb: "The little old lady turtled along the road." Using a noun as a verb has become so common that many nouns have actually become verbs also. For example, "Let's book the flight." The noun "book" is now often used as a verb, as in this example. Other noun-as-verb usages include "I can keyboard that for you," "We need to scissor expenses," and "Desk him." Other substitutions could include an adjective used as a noun, as in "She dove into the foaming wet," interjection as verb, as in "Don't aha me!" a verb as a noun, as in "Help! I need some eat!" and so on.
