Speaking: Grammar in Speaking A2

Using "can/can't" for Ability

Listen to the examples here.

What you will learn: By the end of this lesson, you will be able to talk about your abilities and understand the crucial pronunciation difference between "can" and "can't".

Pronunciation is the Secret 🤫 (Click 🔊)

In spoken English, the difference between "can" and "can't" is not the 't' sound. The difference is the stress and the vowel sound. This is the most important part of the lesson! Listen carefully.

✅ Positive "can" is WEAK

It is unstressed and pronounced quickly, like "k'n". The stress goes on the main verb.

I k'n SWIM.
/aɪ kən swɪm/
❌ Negative "can't" is STRONG

It is stressed and has a clear 'a' sound (like in "cat"). The stress is on "can't".

I CAN'T swim.
/aɪ kænt swɪm/

Grammar Rules for "can"

💡 The Easy Rules

"Can" is a modal verb. It's easy because the rules are simple:

Rule 1: The verb after "can" or "can't" is always the base form (infinitive without 'to').
  • He can speak English. (NOT "speaks")
  • She can't play the guitar. (NOT "plays")
  • We can go tomorrow. (NOT "going")
Rule 2: The form of "can" never changes.

It's the same for all subjects: I can, you can, he can, she can, it can, we can, they can.

Rule 3: To make a question, switch the subject and "can".
  • You can cook. ➡ Can you cook?
  • They can come. ➡ Can they come?

Activity 2: What Can You Do?

Make three true sentences about yourself. Use two with "I can..." and one with "I can't...". Practice saying them aloud, paying attention to the weak 'k'n' and strong 'can't'.

  • ...someone who can speak more than two languages. (Ask: "Can you speak more than two languages?" )
