Helping verbs are verbs that, as their name suggests, help the main verb in a sentence by extending the meaning of the verb. They add detail to how time is conveyed in a sentence. As a result, helping verbs are used to create the most complicated verb tenses in English: the progressive and the perfect aspects.
These verbs also function to convey complicated shades of meaning like expectation, permission, probability, potential, obligation, and direction. In modern linguistics, this class of verbs is called auxiliary verbs. The meanings of these two terms are interchangeable.
