What is special about the modal verbs?

  • 3. To form negative sentences, use the modal verb itself and add "not" or "n't" to it. Examples: "He can run fast enough." Correct: "He can't run fast enough." Incorrect: "He doesn't can run fast enough." "She could lift a feather." Correct: "She could not lift a feather." Incorrect: "She did not could lift a feather." "I thought he would come." Correct: "I thought he wouldn't come." Incorrect: "I thought he did not would come."

How and when do we use modal verbs?

  • Uses of "can" (negative: cannot, can't)
  • 1. To talk about a) ability or b) skill a) "He is so strong! He can lift that engine!" b) "Can he swim?"
  • 2. To talk about a general possibility "The weather here can get really bad." "Such things can happen.“
  • 3. To say that something is allowed "He can borrow my book if he needs it." "You can't smoke in here".
  • 4. To make a request (this is is an informal use, "may" is the formal version) "Can I come in?" "Can you make some tea?"

How and when do we use modal verbs?

  • NOTE: It has just been said that “can” can be used to express an ability to do something.
  • “He can repair the engine.”
  • In the past, we can use “could” or the expression “be able to”:
  • He could repair the engine.
  • He was able to repair the engine.
  • In the future, we can use “be able to” because “can” does not have a future form:
  • He will be able to repair the engine.

How and when do we use modal verbs?

  • Uses of "could" (negative: could not, couldn't)
  • 1. As the past form of "can" "He said he couldn't come so early." "I couldn't remember who he was." "They couldn't pass the border."
  • 2. To make a polite request "Could you open the window, please?" "Could you turn up the heat?" "Could you remind him to call?“
  • 3. To show possibility ("may" and "might" are stronger) "She could be with her parents." "It could take you months to find a new place." "He could still win, but it's not very likely."
