Ad lib redirects here. For other uses, see Ad lib (disambiguation). Ad libitum (/Ã¦dËlÉªbáµ»tÉm/) is Latin for at one's pleasure; it is often shortened to ad lib (as an adjective or adverb) or ad-lib (as a verb or noun).
An adverb is a modifying part of speech. It describes verbs, other adverbs, adjectives, and phrases. They are used to describe how, where, when, how often and why something happens.Here are a few examples:Verb-The cat climbed quickly up the tree.ome adverbs often get overused, such as very, extremely, and really. Using there is/are or it is at the beginning of a sentence adds nothing. Sentences with these adverb phrases become wordy, boring, and less clear. Look at some examples: * There are many bird species living in the sanctuary.
