MODAL VERB: MAY/MAY NOT & MIGHT/ MIGHT NOT

• ​Modal verbs don’t add -s for the third person singular, so the form is always the same.

For example, She can swim.

NOT

She can swims.

• ​The question form is created by inverting the subject and the verb. For example, Will you go?

​

• ​We make the negative form by adding ‘not’. For example, They couldn’t attend the meeting.

• ​They are followed by the verb without ‘to’. For example, "We might watch a movie." 

We don't say; "We might to watch a movie."

• ​They don’t have an infinitive form. When necessary we use another word.

For example, 

She would like to be allowed to arrive ten minutes late. 

#1 RULE:

• ​Possibility/ Prediction (in the past, present & future)

• ​It may rain later on, so take an umbrella.

​#Permission

​When we ask and give permission we often use may as an alternative to can.

​May I come in?

​Positive form: May/ Might

​Negative form: May not/ Might not

*We don’t use don’t / doesn’t /didn’t with may ​

Positive Statement:​

-It may be possible for him to get home tonight.

-This may hurt you.

​

Negative Statement:

-We may not have enough information at the moment.

Not: We don’t may have enough information at the moment.
