Introduction

A modal verb is a type of auxiliary (helping) verb that has no meaning on its own but it modifies the main verb, changes its meaning and gives more details about the action.

The verb can is a modal verb used to express the idea of ability or opportunity, to express the possibility or impossibility of an event or action happening and to ask for or give permission.

Form

The modal verb can is used as an auxiliary verb and has three forms:

Affirmative

Its structure, in the affirmative form, is:

Use

We use can when we express:

  1. Abilities: to be able to do something;
  2. General truths: to talk about things that are usually true;
  3. Offers: to make offers;
  4. Opportunities: to express the chance to do something;
  5. Permissions: to ask or give permission;
  6. Possibilities: to talk about possible situations;
  7. Reproaches: to tell someone what we want them to do;
  8. Requests: to demand something.

Summary

The modal verb can express ability, offer, request, possibility, opportunity, permission, reproach and general truth.

We can use it in its different forms:

  • Affirmative: We start with the subject followed by can and the verb.
  • Negative: We start with the subject followed by cannot and the verb.
  • Interrogative: We start with can followed by the subject and the verb (the sentence ends with a question mark).

For example:
— Affirmative: “She can play the piano.”
— Negative: “She can’t play the piano.”
— Interrogative: “Can she play the piano?

NOTE: The form is always the same, even for the third person singular.
