<h3>What are helping verbs?</h3>
Whether they do so by conveying time, voice, possibility, necessity, obligation, or other crucial information, or by assisting in the framing of a question, supporting verbs provide additional information to the main verb. For the record, verbs are words that describe an action or state of being. Auxiliary verbs are another name for helping verbs (or auxiliaries). The most typical auxiliary verbs are, do, and have (in all of their forms), but there are also modal auxiliaries, commonly known as modals or modal verbs. In other words, while all auxiliary verbs are models, not all auxiliary verbs are helping verbs.
