What are Modal Verbs?
Modal verbs are special verbs which behave very differently from normal verbs. Here are some important differences:
1. Modal verbs do not take "-s" in the third person.
Examples:
He can speak Chinese.
She should be here by 9:00.
2. You use "not" to make modal verbs negative, even in Simple Present and Simple Past.
Examples:
He should not be late.
Theymight not come to the party.
3. Many modal verbs cannot be used in the past tenses or the future tenses.
Examples:
He will can go with us. Not Correct
She musted study very hard. Not Correct
Common Modal Verbs
|Can |Ought to |
|Could |Shall |
|May |Should |
|Might |Will|
|Must |Would |
Can means that a person is physically able to do something.
May means does a person have permission to do something.
For example:
Student: "Miss, can I sit in this chair?"
Teacher: "Yes, you can but you may not."
Should=you don't have to do it.
Must=you have to do it...no choice.
Must is used to express obligation, necessesity, it isa certainty or extreme likelihood.
Should only expresses probability
IT reflects the severity of importance.
Ex:
You really SHOULD see a doctor about that sore throat.
You MUST get that lump checked out unless you want to get sick.
Shall is properly the form of the future indicative auxiliary in the first person: I shall go, we shall go. In all other persons, the form is will: you will go,she will go, they will go. This distinction is all but extinct in everyday speech.
These forms are reversed when it takes the form of a command: I will be heard means I demand to be heard, and It shall be done means it will and must be done.
Might
Past tense of, may.
Used to indicate a condition or state contrary to fact: She might help if she knew the truth.
Used to indicate a possibilityor probability that is weaker than may: We might discover a pot of gold at the end of the rainbow.
Used to express possibility or probability or permission in the past: She told him yesterday he might not go on the trip.
Used to express a higher degree of deference or politeness than may, ought, or should: Might I express my opinion?
Could Past tense of, can.
Used to indicate ability orpermission in the past: I could run faster then. Only men could go to the club in those days.
Used with hypothetical or conditional force: If we could help, we would.
Used to indicate tentativeness or politeness: I could be wrong. Could you come over here?
Ought, Should. Usage: Both words imply obligation, but ought is the stronger. Should may imply merely an obligation of propriety, expendiency,etc.; ought denotes an obligation of duty.
