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 English.
• She should  be here by 7:00.

2. You use "not" to make modal verbs negative, even in Simple Present and Simple Past.

Examples:

• He should not be late.
• They might 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
