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 Russian. She should go now. My wife may join us for the dinner.
2. You use "not" to make modal verbs negative, even in Simple Present and Simple Past. EXAMPLES: You should not be late. I can not come to at 6pm. He may not like this idea. You must not disturb him now, he is busy.
3. Many modal verbs cannot be used in the past tenses (MUST) or the future tenses (CAN). Have to i nstead of must Be able to i nstead of can EXAMPLES: He will be able to go with us. She had to study very hard.
4. After a modal verb infinitive forms don’t have the preposition TO. EXAMPLES: She can to play the piano very well She can play the piano very well They must to go home. They must go home.
