MODALS

Modals or Modal Auxiliaries are forms of auxiliary verbs that are generally used before the main verbs. They are used to express mood, ability, possibility, permission, obligation, etc.

1.       Actual Modals: Shall, should, will, would, can, could, may, might, must, ought to

2.       Semi-Modals: Used to, need, dare

Rules of Modals

1.       Always use V1 (base form of verb) after a modal verb. Never use V2, V3, V4, V5, infinitive (to + V1), noun or adjective immediately after a modal verb.

Example:

Correct: He will be going to Patna.
Incorrect: He will going to Patna.

Correct: She would have written a letter.
Incorrect: She would written a letter.

Correct: He may be a doctor.
Incorrect: He may a doctor.

2.       Never use two modals together.

Correct: It may rain today.
Incorrect: It will may rain today.

Correct: He must be a student.
