A verb phrase is a group of words that includes a main verb and any auxiliary (helping) verbs. For example, in the sentence "She is running," the verb phrase is "is running," where "is" helps to show the ongoing action of "running." Verb phrases can also include modifiers or complements that provide more information about the action. Verb phrases can express different tenses, moods, and aspects. For instance, "has been studying" indicates an action that started in the past and continues into the present. Understanding verb phrases is essential for constructing clear and grammatically correct sentences in the English language.
