Modal Verbs

What are Modal Verbs?

Modal verbs are auxiliary verbs that express necessity, possibility, permission, or obligation. The primary modal verbs in English include can, could, may, might, must, shall, should, will, and would. These verbs are unique in that they do not change form according to the subject and are always followed by the base form of the main verb without ‘to’. Modal verbs are used to adjust the mood of the main verb, allowing the speaker to convey attitudes about the likelihood, necessity, or obligation of the action being discussed. For example, in the sentence “She can swim,” the modal verb “can” indicates ability.

List of Modal verbs

Modal verbs are auxiliary verbs that express various degrees of necessity, probability, permission, or obligation. Here’s a brief overview of common modal verbs in English, each with an example to illustrate its use:

Can:

• Indicates ability or possibility.
• Example: “I can speak three languages.”

Could:

• Used for past ability, or present possibility, often more polite or speculative than “can.”
• Example: “She could come over after work.”

May:

• Expresses permission or possibility, slightly more formal than “can.”
• Example: “You may enter the room now.”

Might:

• Indicates a slight possibility or speculative condition.
• Example: “It might rain later today.”

Must:

• Shows necessity or strong obligation.
• Example: “You must wear a seatbelt while driving.”

Shall:

• Traditionally used for future actions, particularly in formal or British English, often involving suggestions or offers.
• Example: “Shall we go to the cinema tonight?”

Should:

• Indicates advice, recommendations, or expectations.
• Example: “You should check your answers before submitting the test.”

Will:

• Expresses future intentions or facts.
• Example: “I will be there by 8 PM.”

Would:

• Used for hypothetical situations or politeness, often in conditional sentences.
• Example: “I would go with you if I had the time.”

How to use modal verbs (with examples)

Modal verbs are a unique class of verbs in English that add meaning and intention to the main verb in a sentence. They help express abilities, possibilities, necessities, and permissions, which are crucial for effective communication. To correctly use modal verbs, one must remember that they always precede the base form of the main verb without “to”. For example, in the sentence “She can play the piano,” “can” is the modal verb showing ability, and “play” is the main verb in its base form.

When expressing possibility or likelihood, modal verbs such as “may,” “might,” and “could” are used. These modals help to soften statements, making them less direct or certain, which can be particularly useful in speculative or polite contexts. For instance, “He might join us later,” suggests a possibility without certainty. Similarly, “You could see a doctor if the pain continues,” implies a suggestion with a polite undertone.

For indicating necessity or obligation, “must” and “should” are commonly employed. “Must” conveys a strong sense of necessity, often linked to personal convictions or external rules, as in “You must stop at a red light.” On the other hand, “should” is used to recommend actions or to imply a lighter form of obligation, suitable for giving advice, such as “You should take your medication to feel better.”

Lastly, to express permission or prohibition, “can,” “may,” and “shall” are the appropriate choices. “Can” and “may” offer permission, but “may” sounds more formal and polite, as in “May I leave the table?” In contrast, “shall” is more commonly used in formal or British English to make offers or suggestions and can sometimes be used in legal or regulatory statements. Understanding the specific contexts and nuances of each modal verb enriches communication, allowing for clear expression of different levels of formality, certainty, and obligation.
