‘Author’ is a Verb.

Only one can be both a noun and a verb. The noun “author” first appeared in Middle English around the early 14th century, the Oxford English Dictionary says, with two similar meanings: a creator, inventor, founder, or constructor of something; or a writer of books or other works.

We do not currently know of any adverbs for wrote. Using available adjectives, one could potentially construct nonstandard adverbs such as writably, writatively, writeably, writerishly, writerlessly, writerlily, writlessly, writtenly or writingly.

authorship

The word ”book” on its own is a common noun. It refers to a written or printed publication that is bound by a cover.

Bookstore is an example of a closed compound word. It is always written as one word, and it is an American word that dates back to the mid-1700s. Today, it can be used to mean a physical store or an online store that sells books.

Every noun can further be classified as common or proper. A common noun names general items. Teenager, grandmother, salesclerk, police officer, toddler, manager, window dresser, janitor, shoplifter—all of these people are common nouns. The important thing to remember is that common nouns are general names.
