Topic: Auxiliary verb

Auxiliary verbs are 'helping verbs', which always accompany the main verb. They help to form questions, negatives and passive sentences, and to express aspect.

Politeness and directness

This task is about using verbs and modal verbs in different ways. We all know that people can be direct or indirect in the ways they phrase things. We often use imperative forms to give instructions, but sometimes these might be seen as too direct and blunt. We sometimes soften them with modal verbs, among other tools.

Politeness and directness: Activity

Try to make the following expressions less direct. Compose alternative sentences for each one.

  1. Shut the window.
  2. Tell me your name.
  3. Stop talking.

What changes did you make to render the expressions less direct? 

Now, make the following expressions more direct. Compose an alternative sentence for each example.

Verbs have traditionally been described as ‘doing words’ or ‘action words’. This works well for some verbs, like sprint, chatter, eat. Here are some sentence examples with verbs which describe actions:

Verbs: Auxiliary verbs

A key distinction in the word class of verbs is between main verbs (also called lexical verbs) and auxiliary verbs:

Verbs: Modal verbs

Modal auxiliary verbs (or modals for short), as the name suggests, are a kind of auxiliary verb. They have most of the attributes of auxiliary verbs. They are a closed class that is identifiable as a short list, and they convey particular types of meaning.

Here is a table which lists the most important modal verbs (also called the core modals). It shows most of them in pairs as present and past tense forms, which makes them easier to remember.

Verbs: Nonfinite and finite

Verbs can be divided into finite and nonfinite forms. Finite verbs carry tense. So, past and present tense verb forms are finite. Nonfinite verbs do not carry tense, and do not show agreement with a Subject. Put differently, they are not 'limited' by tense or agreement.

The infinitive form of a verb is nonfinite. It is the form which follows to:

Verbs: Tense

Tense is a grammatical notion that refers to the way in which a language encodes the real world notion of time. Typically this is done through endings on verbs called inflections. Verbs are the only word class that can carry tense inflections (though they don't always do so). Verbs that carry a tense ending are called finite verbs.

Auxiliary verbs
