What Are Modal Verbs?
Modal verbs are auxiliary verbs that express attitudes or functions like possibility, necessity, permission, and ability. Common modal verbs include:
-
Can
-
Could
-
May
-
Might
-
Must
-
Shall
-
Should
-
Will
-
Would
Unlike regular verbs, modal verbs do not change form according to the subject, and they are always followed by the base form of a verb.
For example:
-
She can swim. (not She cans swim)
-
They should go. (not They should goes)
Understanding how to use these verbs will help you speak more accurately in various situations.
Using Can and Could
Can is commonly used to express ability or permission.
-
I can speak English fluently.
-
Can I borrow your pen?
Could is the past form of can, but its also used in polite requests or when talking about possibilities.
-
When I was younger, I could run faster.
-
Could you help me with this file?
In spoken English, using could instead of can often sounds more polite and respectful, especially when making a request.
Using May and Might
These modal verbs express possibility, but may is slightly more formal or certain than might.
-
It may rain later.
-
He might join us for dinner.
In spoken English, might is often preferred because it's more casual and commonly used in everyday conversations. However, both are acceptable depending on the tone and context. Understanding such subtle differences is essential for learners preparing for speaking exams, and enrolling in a reputed IELTS Coaching in Chennai can help you master these nuances effectively.
May is also used for formal permission:
-
May I come in?
In casual settings, people usually use can instead:
-
Can I sit here?
Using Must and Have to
Must expresses strong necessity, obligation, or logical deduction.
-
You must wear a seatbelt.
-
She must be at home. The lights are on.
Have to also shows necessity but is more commonly used in informal spoken English:
-
I have to finish my assignment today.
Must is more common in written or formal English, while have to fits better in conversation.
Using Should and Ought to
Both these modal verbs are used to give advice or express moral obligation.
-
You should eat more vegetables.
-
We ought to respect our elders.
In everyday speech, should is far more commonly used than ought to. Its simple, direct, and easier to pronounce.
-
You should see a doctor. (More natural in speech than ought to)
Using Will and Would
Will is used to talk about future actions or promises.
-
I will call you tomorrow.
-
She will be here by 6 PM.
Would is used for polite requests, hypothetical situations, or as the past of will.
-
Would you like some coffee?
-
If I were you, I would apologize.
In spoken English, would helps soften your tone and make your requests sound more polite and considerate.
Politeness in Spoken English
Modal verbs play a big role in sounding polite and respectful. Lets compare two requests:
-
Give me the book. (Direct and can sound rude)
-
Could you give me the book, please? (Polite and appropriate)
In conversations, especially with strangers or in professional settings, modal verbs like could, would, and might are preferred to create a positive impression.
Modal Verbs for Expressing Possibility and Uncertainty
Spoken English often involves expressing uncertainty or probability. Modal verbs help do this subtly and clearly.
-
He might be at the caf.
-
They could be stuck in traffic.
-
We may arrive late.
These phrases show that youre not 100% sure but give the listener important context.
Common Mistakes to Avoid
When using modal verbs in spoken English, here are some typical errors to watch out for:
? She cans swim.
? She can swim.
? He musts go now.
? He must go now.
? I should to call her.
? I should call her.
Modal verbs are never used with -s endings or with to before the main verb (except for ought to).
