Modal verbs are verbs that are used to give meaning to action verbs in a sentence. They are combined with the main verb to express certainty, obligation, possibility, or permission; therefore, they change the purpose of a statement and give the intention of sentences. We can agree that all sentences in a conversation are different. Modal verbs are used to describe the various meanings of the sentences.
Modal Verbs
What Are Modal Verbs?
Modal verbs are words like shall/ should, may/ might, must, and can/ could. These are helping verbs that support action verbs in giving meaning to a sentence or clause. When used with the main verb, they can express ability, probability of action, permission, or obligation to do something. For example, when you say, I can ride a boat. “Can” is the modal verb describing ability.
Rules to Follow When Using Modal Verbs
- The modal verb always appears before the action verb. Modal verbs always appear before the main verb and not after.
- Do not use the infinitive “to” before the main verb after using the modal verb. Except when using “ought to“, which is also a modal verb. For example, “She must to let go.” Is incorrect.
- “Not” is added after the modal verb if the verb needs to be negated.
- Modal verbs are used as they are; they do not change with the tense.
Modal Verbs vs. Auxiliary Verbs
Modal verbs and auxiliary verbs are combined with the main verb to give different meanings to sentences. Auxiliary verbs express tenses, ask questions, to express negation or grammatical aspects. In contrast, modal verbs describe permission, obligation, ability, or suggestion. Modal verbs are a type of auxiliary verbs, but the difference between the common auxiliary verbs and modal verbs is that modal verbs remain unchanged when used in sentences; they are not subjected to any inflection.
Types of Modal Verbs
Modal verbs are auxiliary verbs that are used to express modality, which is the speaker’s attitude towards the action or state described by the main verb. There are nine modal verbs in English: can, could, may, might, will, would, shall, should, and must. Each of these modal verbs has its own specific meaning and usage.

Modal Verbs in Different Tenses
Present Tense
In the present tense, modal verbs can indicate ability, permission, and possibility. For example, “She can speak Spanish fluently,” “You may leave the room now,” and “It might rain later.”
Past Tense
Some modal verbs can also be used to indicate past time, such as “could” and “might.” For example, “She could play the piano when she was younger,” and “He might have forgotten his keys at home.”
Future Tense
Modal verbs can also be used to indicate future time, such as “will” and “shall.” For example, “I will meet you at the train station tomorrow,” and “Shall we go to the movies tonight?”
Conditional Tense
Modal verbs can also be used in the conditional tense to indicate possibility or hypothetical situations. For example, “If I had more money, I could buy a new car,” and “She might come to the party if she finishes her work on time.”
It’s important to note that not all modal verbs can be used in all tenses. For example, “must” is typically only used in the present tense to indicate obligation or necessity.
Modal Verbs in Questions and Negatives
Modal verbs are often used in questions and negatives to express a variety of meanings, such as ability, possibility, permission, and obligation. In this section, we’ll explore how modal verbs are used in questions and negatives and provide some examples to help you better understand their usage.
Questions with Modal Verbs
Modal verbs are often used in questions to ask for permission, make requests, or express uncertainty. In questions, the modal verb usually comes before the subject of the sentence. For example:
- Can he come to the party?
- Would you mind closing the window?
- Should we go to the beach today?
In the first example, “can” is used to ask for permission. In the second example, “would” is used to make a polite request. In the third example, “should” is used to express a suggestion.
Negatives with Modal Verbs
Modal verbs are also used in negatives to express prohibition, inability, or lack of necessity. In negatives, the modal verb is usually followed by “not”. For example:
- You must not smoke in here.
- I cannot speak Spanish.
- She need not worry about the test.
In the first example, “must not” is used to express prohibition. In the second example, “cannot” is used to express inability. In the third example, “need not” is used to express lack of necessity.
It’s important to note that some modal verbs have different negative forms. For example, “should” becomes “should not” in negatives, while “must” becomes “must not”.
Common Mistakes with Modal Verbs
Modal verbs can be tricky to use correctly, and many people make common mistakes when using them. Here are some of the most common mistakes people make with modal verbs:
Mistake 1: Changing the Form of the Modal Verb
One of the most common mistakes people make with modal verbs is changing their form. Modal verbs should be used as they are, without changing their form to present, future, or past tense. For example, “Joan can swim” is correct, while “Joan cans swim” is incorrect. Similarly, “He might go to sleep” is correct, while “He mights go to sleep” is incorrect.
Mistake 2: Adding Words to Modal Verbs
Another common mistake people make with modal verbs is adding words to them. Modal verbs should be used on their own, without adding “s”, “ed”, or “ing” to them. For example, “She will go to Spain next month” is correct, while “She wills go to Spain next month” is incorrect.
Mistake 3: Using the Wrong Modal Verb
Using the wrong modal verb is also a common mistake people make. Each modal verb has a specific meaning and should be used accordingly. For example, “can” expresses ability, “should” expresses advice or recommendation, and “must” expresses obligation. Using the wrong modal verb can change the meaning of the sentence and lead to confusion.
Mistake 4: Using Modal Verbs to Ask for Permission
Another common mistake people make with modal verbs is using them to ask for permission. Modal verbs should not be used to ask for permission, but instead should be used to express ability, advice, obligation, or possibility. For example, “Can I go to the movies?” is incorrect, while “May I go to the movies?” is correct.
By avoiding these common mistakes, you can use modal verbs correctly and effectively in your writing. Remember to use them as they are, without changing their form or adding words to them, use the appropriate modal verb for the situation, and avoid using them to ask for permission.
