What is modal verbs?
odal verbs are auxiliary verbs which are used in the sentences to refer possibility, ability, advice, permission, obligation and others. However, modal phrases are used in the sentences to express the same things. The modal verbs are also known as helping verbs or modal auxiliaries.
A list of modal verbs:
Can, Could, Will, Would, May, Might, Shall, Should, Must.
Rules to Use Modal Verbs:
• ‘Not’ is used after the verb to refer a negative meaning.
• Modal verbs are placed before the subject in questions.
• Modal verbs are not changed according to the tense.
• Infinitive verbs are used after the modal verbs.
Examples of Modal Verbs:
Can (Ability) — I can write Bengali.
Can (Possibility) — Smoking can deteriorate the health.
Can (Permission) — Can I use your mobile for once?
Could (Ability in the past) -I could not speak Bengali.
Could (Possibility) — It could rain in this week.
Could (Polite permission) — Could I use your mobile phone?

in use
Can expresses the ability or ability to perform an action: I can, I can. It is used in two forms: can — in the present tense and could — in the past tense and subjunctive mood.

  • can — present
  • could — past tense and subjunctive mood, as well as in the present tense for polite requests
In negative sentences, the particle not is added to both verbs: can/can't, could/couldn't.

Let's consolidate the information — the table will help us with this. In it, we will show a scheme for the formation of affirmative, negative and interrogative sentences with the modal verbs can and could.
