Verbs describe actions--what has happened, what is happening, or what will or might happen--or a condition.
Verbs can be divided into two categories, transitive and intransitive. A transitive verb takes an object; an intransitive verb does not.
Verbs must always agree with their subjects.
Sometimes with the addition of auxiliary verbs, verbs express
Each of these categories is expressed with a particular verb form (base form, present participle, or past participle). Although the vast majority of English verbs are regular, many of the most commonly used verbs are irregular.
Verbs can be modified, or described, by adverbs.
