Understanding Modal Verbs: Can and Could Explained

Learning English grammar can be easy if you start with the basics. One of the most useful parts of English grammar is modal verbs. These verbs help us express different ideas such as ability, permission, and possibility. In this blog, we’ll focus on two important modal verbs: can and could.

We’ll cover the definition of modal verbs, provide examples, and share how you can use them in daily life. By the end of this blog, you’ll feel more confident using modal verbs in your own sentences.

What Are Modal Verbs?

  • Modal verbs are special helping verbs. They work with main verbs to add meaning. These verbs include:

    • can
    • could
    • may
    • might
    • will
    • would
    • shall
    • should
    • must
    • ought to

    Each modal verb expresses a different function. Some show possibility. Some show ability. Others are used for permission or polite requests.

Modal Verb: Can

  • 1. To Show Ability

    We use can to talk about skills or talents. It shows what someone is able to do.

    Examples:

    • She can drive a car.
    • I can swim.
    • They can play the guitar.
    • We can speak English fluently.

       

    In these sentences, “can” shows the ability to do something.

    2. To Show Possibility

    Can also shows that something is possible.

    Examples:

    • It can rain this evening.
    • He can finish the work by 5 p.m.
    • You can get a good score with practice.

       

    These sentences show that something might happen.

    3. To Give Permission

    Can is often used to allow or ask for something.

    Examples:

    • Can I use your phone?
    • You can leave early today.
    • Can I ask a question?

    These are examples of giving or asking for permission.

Modal Verb: Could

  • Could is the past tense of can, but it also has other uses. Let’s look at them.

    1. To Show Ability in the Past

    We use could when talking about what someone was able to do in the past.

    Examples:

    • When I was young, I could run fast.
    • He could sing beautifully.
    • She could solve difficult puzzles easily.

    These sentences talk about skills people had in the past.


    2. To Show Possibility (Past or Future)

    Could also shows possibility. It’s more polite or uncertain than “can.”

    Examples:

    • You could get a better job with this course.
    • We could go to the beach tomorrow.
    • The train could be late.

    This use shows that something might happen or might have happened.

    3. To Make Polite Requests

    Could is more polite than “can” when asking someone to do something.

    Examples:

    • Could you help me with my homework?
    • Could you open the window, please?
    • Could I borrow your pen?

    This form is often used in formal or respectful situations.
