* "May" is a modal auxiliary verb, indicating possibility or permission.
* "Verb phrase" is a group of words that contains the main verb of a sentence and any helping verbs.
Therefore, "may" cannot stand alone as a verb phrase. It needs a main verb to form a complete verb phrase.
Example:
* May *go* (Verb phrase: may go)
* May *have gone* (Verb phrase: may have gone)
In these examples, "may" acts as a helping verb, combining with the main verbs "go" and "have gone" to form complete verb phrases.
