The verbs in a sentence can fall into three categories: main, auxiliary and copular.

Main verb
- A main verb describes the main action of the clause.
- For example, eats, sleeps and walks.

Main verbs - examples

Auxiliary verb
- An auxiliary verb is a verb which helps the main verb of the sentence.
- For example, do and be.
- These verbs can also be used to express possibility.
- For example can, might and will. These particular auxiliary verbs are described as modal auxiliary verbs.

Auxiliary verbs - examples
- I am waiting for the bus.
- Here, waiting is the main verb and am is the auxiliary verb used to form the present progressive tense.

Copular verb
- A copular verb links the subject to a noun or adjective that complements the subject.
- The most common copular verb is the verb ‘is’ (and all of its conjugations like am, were and are).
- Other examples are: appear, seem, look, sound, smell, taste, feel, become and get.

Copular verbs - examples
- The food tastes amazing.
- Here, 'food' is the subject and 'amazing' is the adjective complementing the 'food'. So 'tastes' is the copular verb.
- Henry is bad at football.
- Here, 'Henry' is the subject and 'bad' is the adjective complementing 'Henry'. So 'is' is the copular verb.
- Margaret feels angry.
- Here, 'Margaret' is the subject and 'angry' is the adjective that complements 'Margaret'. So 'feels' is the copular verb.
