ESA PEDIA: MODAL VERBS

Hello, ESAHolics!

ESA FKIP Universitas Riau is pleased to share another English learning topic through this blog to support your understanding of grammar. In this blog, we will discuss Modal Verbs, an essential part of English that helps speakers express meaning beyond simple actions.

In English grammar, modal verbs are commonly used to show ability, possibility, necessity, permission, and other attitudes toward an action. Although they are short and often overlooked, modal verbs play a crucial role in shaping meaning and intention in both spoken and written communication. Through this blog, readers will gain a clear understanding of what modal verbs are and when they are used in everyday English.

WHAT ARE MODAL VERBS?

Modal verbs are a type of auxiliary (helping) verbs used to express meanings such as possibility, ability, intention, permission, and necessity. They do not describe actions directly, but instead modify the meaning of the main verb in a sentence. In English, modal verbs are always used together with the base form of another verb (the infinitive without to). Their function is to add nuance, showing whether an action is possible, required, suggested, or uncertain.

Modal verbs are commonly used to express hypothetical or non-factual situations, rather than statements that are absolutely certain. Because of this, they are often found in sentences that involve opinions, conditions, or potential outcomes. Since modal verbs act as helpers, they generally cannot stand alone in a sentence. However, a modal verb may appear by itself when the main verb is clearly understood from the context. 

WHEN ARE MODAL VERBS USED IN ENGLISH?

English modal verbs are used to express different conditions related to meaning and attitude. They help explain how likely something is, whether an action is possible, required, suggested, or done out of habit. Below are the main situations in which modal verbs are commonly used.

1. Likelihood

Modal verbs can be used when something seems probable but cannot be stated as an absolute fact. In these situations, speakers use should or must to show a strong assumption rather than certainty. 

Example:

She left early, so she must be at home by now.

2. Possibility

When an action or situation is possible but uncertain, modal verbs such as could, may, or might are used to show that the outcome is not guaranteed.

Example:

It might rain this afternoon.

3. Ability

The modal verb can is used to indicate whether someone is capable of doing something. Its negative form, cannot shows inability.

Example:

He can solve complex math problems.

4. Permission

Modal verbs are often used to ask for or give permission. Commonly used modals for this purpose include can, may, and could. In more formal situations, may is traditionally considered more polite, although can is widely accepted in everyday conversation.

Example:

May I leave the room for a moment?

5. Request

To politely ask someone to do something, speakers often use will, would, can, or could. The level of politeness depends on the modal chosen and the context.

Example:

Could you help me with this assignment?

6. Suggestion or Advice

When giving advice or recommending an action without forcing it, the modal verb should is commonly used.

Example:

You should get some rest before the exam.

7. Command

Modal verbs can also be used to give strong instructions or commands. In these cases, must, have to, or need to are used. Unlike true modal verbs, have to and need to keep the word to before the main verb.

Example:

You must submit the form today.

8. Obligation or Necessity

To express duties, requirements, or necessary actions, modal verbs such as must, have to, and need to are used. Their negative forms indicate that an action is not required.

Example:

She has to attend the meeting tomorrow.

9. Habit

Modal verbs can describe actions that happen regularly. The modal will is used for present or future habits, while would and the phrase used to are used to talk about habits in the past.

Example:

When he was a child, he would read before bed every night.
