Helping verbs are verbs that help the main verb in a sentence by extending its meaning. They can also 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.
Helping verbs are important since they are needed to make up the structure of a sentence. They are used to help the main verb. There are two types of verbs that can be used as helping verbs in English: auxiliary and modal.
Auxiliary Verbs: Helping verbs that add meaning to the clause where they are being used are called auxiliary verbs (note that the terms helping verb and auxiliary verb are often interchangeable). They are used to express tense or to add emphasis. The three common auxiliary verbs have multiple forms:
Be, do, and have can be either standalone or auxiliary verbs. You can tell when these verbs are auxiliary if they are teamed with other verbs to complete the verb phrase. The following sentences are examples of auxiliary verbs:
Modal Verbs: Helping verbs that perform other specific tasks to further modify the action or meaning of the main verb are called modal verbs. Modal verbs do not change form. They are:
Modal verbs help to show obligation, possibility or necessity in a sentence. The following sentences are examples of modal helping verbs:
Different helping verbs are used for different purposes in sentences. One of the auxiliary verb's main functions is to situate the action of a sentence in a particular aspect of time. The two main aspects that auxiliary verbs play a role in are the progressive aspect and the perfect aspect.
When the main verb in a sentence ends in -ing, the progressive aspect is often being used. This aspect is used to convey the notion that an action is occurring in an ongoing fashion.
The forms of the helping verb to be (am, is, are, was, and were) are used to create this aspect:
There are three different forms of the perfect aspect in English: past perfect, present perfect, and future perfect. The perfect aspect is used to explain an action that is/was/will be in a state of progress and is/was/will be completed before a particular time. The perfect aspect can also be used in the continuous form to show actions that are ongoing.
Forms of the verb to have and to do are often used to create the various perfect aspects.
The perfect aspect is subdivided into:
The following sentences demonstrate how helping verbs are used to create these aspects:
One important rule to keep in mind is that the verb phrase in a sentence should not include more than three helping verbs.
When used properly, helping verbs perform some of the most intricate work in English verb phrases. The more complex aspects, progressive and perfect, should be approached by writers who already have an advanced understanding of English sentence structure.
For second language learners, helping verbs can pose particular problems and should therefore be studied after a solid foundation of simple verbs has been achieved.
