Modal verbs are auxiliary verbs like can, must, and should that express ability, permission, obligation, and possibility. They are fundamental for precise English communication but have unique rules that often confuse learners. This guide demystifies modal verbs with clear explanations, essential tips, and over 100 practical examples to solidify your understanding.
Introduction to Modal Verbs
Modal verbs are a special class of auxiliary verbs in English that modify the main verb to convey concepts such as possibility, necessity, permission, and ability. Unlike most verbs, they don’t change form and have specific grammatical rules. A strong command of modal verbs is crucial for achieving fluency and is frequently tested in competitive exams and academic assessments.
What Are Modal Verbs?
The core modal verbs in English are: can, could, may, might, will, would, shall, should, must. The verbs ought to, need to, and used to are also often included in this category due to their similar functions. Their primary role is to indicate the speaker’s attitude or stance towards the action described by the main verb.
Key Rules for Using Modal Verbs
- No Inflections: They do not add ‘-s’, ‘-ing’, or ‘-ed’. (e.g., She can sing. Not: She cans sing).
- Base Form Following: They are followed directly by the base form of another verb (e.g., You must try). The exception is ‘ought to’.
- No ‘To’ Needed: They are not used with the infinitive ‘to’ (except ‘ought to’).
- Question Formation: Form questions by inverting the modal verb with the subject (e.g., Could you help me?).
- Negation: Form negatives by adding ‘not’ after the modal verb (e.g., You should not go).

Modal Verbs: Important Tips for Exams and Students
- ‘Shall’ vs. ‘Will’: Traditionally, ‘shall’ was used with ‘I’ and ‘we’, but in modern English, ‘will’ is used for all subjects. ‘Shall’ remains for very formal contexts, legal language, and offers (Shall I…?).
- Past Forms: Most modals don’t have a true past tense. We use phrases like was able to (for can), had to (for must), and was allowed to (for may).
- Probability Ladder: Think of possibility on a scale: might (low) < may/could (medium) < should (high probability) < must (virtual certainty).
- ‘Had better’ vs. ‘Should’: ‘Had better’ implies a negative consequence if the advice isn’t followed. It’s stronger than ‘should’.
FAQs on Modal Verbs
Q1: What is the difference between “may” and “can” when asking for permission?
While both are used, “may” is considered more formal and polite. “Can” is perfectly acceptable in everyday spoken English, but in formal writing or situations, “may” is preferred (e.g., “May I use the restroom?”).
Q2: How do I express the future with modal verbs?
The modal verb “will” is the primary verb used for the future tense. However, other modals can also indicate future actions from a present perspective, such as may (future possibility), must (future obligation), or can (future ability).
Q3: Can we use “must” in the past tense?
No, “must” does not have a past tense form. To express obligation in the past, we use “had to” (e.g., “I had to finish my work yesterday.”). For a logical conclusion about the past, we use “must have” + past participle (e.g., “She must have left already.”).
