In English, many nouns have become verbs. For example, the noun "book" is now often used as a verb, as in the example "Let's book the flight". 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.
