Take any book you want. Are there any messages for me? Any child would love that. Give me any food you don't want.
any (pron.) (used with a sing. or pl. verb)
Any one or more persons, things, or quantities.
To any degree or extent; at all: didn't feel any better.
When used as a pronoun, any can take either a singular or plural verb, depending on how it is construed: Any of these books is suitable (that is, any one). But are any (that is, some) of them available? • The construction of any is often used in informal contexts to mean “of all,” as in He is the best known of any living playwright. In an earlier survey this example was unacceptable in writing to 67 percent of the Usage Panel. • Any is also used to mean “at all” before a comparative adjective or adverb in questions and negative sentences: Is she any better? Is he doing any better? He is not any friendlier than before. This usage is entirely acceptable. The related use of any to modify a verb is considered informal. In writing, one should avoid sentences like It didn't hurt any or If the child cries any, give her the bottle.
