Here's a breakdown:
* Helping verb: This is a verb that assists the main verb in a sentence. Examples include "is," "are," "was," "were," "have," "has," "had," "will," "would," "can," "could," "may," "might," "should," and "must."
* Article: This is a word that comes before a noun to specify whether it is singular or plural, and whether it is definite or indefinite. Examples include "a," "an," and "the."
* Noun: This is a word that names a person, place, thing, or idea.
Example:
* "Is" (helping verb) "a" (article) "cat" (noun)
The entire phrase "is a cat" is the verb phrase.
It's important to note that a verb phrase can include other parts of speech as well, but the core elements are a helping verb and a main verb.
