Modal Verbs for IELTS Speaking and Writing (Can, Could, Might, Should)

Learning modal verbs in IELTS, those that the examiner is looking out for, is one of the best decisions you can make if you wish to achieve a better band score. The small words such as “can”, “could,” “might,” and “should” can alter the entire sentence structure. They will make you appear polite and careful while responding. It is very common for most test takers to neglect these terms, yet they end up losing unnecessary points unknowingly.

Using the modal verb correctly in either the Speaking or Writing section could make your answer seem like it came from an English-speaking pro.

Why Are Modal Verbs Important for IELTS?

The IELTS scoring system appreciates range. Two out of the four components in IELTS are related to structure range and accuracy, grammatical range and accuracy, and lexical resource. Modal verbs will allow you to demonstrate the range of your linguistic skills almost effortlessly.

Here is a comparison of two answers to an IELTS question. 

First variant: “I think tourism is good for the economy.”

Second one: “Tourism could be useful for the economy, however, it could also lead to an increase in the cost of living.”

In the second case, you have expressed probability. Your opinion sounds more realistic and believable. Hedging is precisely what examiners look for at Bands 7 and up.

There is one more reason. Modal verbs make your language more cohesive, fluent and appropriate. Expressing an opinion in the essay, you almost never want to state it definitively. Words like may, might or could will allow you to express an idea tentatively, which is characteristic of educated speech and writing. Developing this habit will improve your score instantly, which is why modal verbs become the first thing trainers correct.

If you are trying to get a modal verbs IELTS band 9 score, these words are obligatory.

What Are Modal Verbs?

Modal verbs are also called modal auxiliary verbs, which are just helping verbs preceding another verb in changing the meaning of the verb. Some of the examples of modal auxiliaries are can, could, may, might, shall, should, will, would, and must. Some grammar books in English call the modal auxiliaries modal aux verbs or modal auxiliary words; however, both terms are identical. You will also come across the term modal verbs and auxiliary verbs because all modal verbs function as auxiliary verbs.

Here is an important feature of modal verbs in English. Modal verbs never take any other forms. You will never put an “s,” “ed,” or “ing” to them. The verb succeeding modal verbs is always in its basic form.

Correct: “She can swim.”

Wrong: “She cans swims.”

This is how all the ideas about auxiliaries and modals work. The idea here is that the auxiliaries help out with the main verb and show us the idea of ability, possibility, permission, suggestion, or obligation. With just this short modal verbs list for IELTS, all is clear!

There are some other verbs that can be classified as semi-modal verbs for IELTS. These include “be able to,” “have to,” and “ought to.” Let us have a look at them.

Modal Verbs: Can, Could, May, Might, and Be Able To

This is the “can,” “could,” “may,” “might,” and “should” vocabulary that you will be using all the time. I’m going to explain the meaning of each one in clear English.

Can and Could (Ability and Possibility)

“Can” means present ability or general possibility. 

“Could” means past ability or a more polite form of can. 

This includes how we say things like “can/could/be able to” in ability expressions.

• “I can speak three languages.”

The difference between “can” and “could” in IELTS is basically time and politeness. In the Speaking test, “could” is a better option for polite requests. 

“Could you please repeat the question?” sounds less direct than its “can” counterpart. These modal verbs for IELTS speaking make a good impression on the examiner.

Can vs Be Able To

There is often confusion between “can” and “be able to.” These terms have the same meaning, although “be able to” can be used in certain tenses where you cannot use “can”. 

“I will be able to do it” instead of “I will can do it.” This is why “be able to” comes in very handy when dealing with future and perfect tenses.

May and Might (Possibility and Probability)

Both these terms are used to indicate possibility, which is not certain.

• It may rain tomorrow.
• Prices might rise next year.

So what about “may” vs “might” in IELTS? There is not much difference between these two forms of English language while conversing in an informal way. “May” appears to be more formal and it is also used for seeking permission (may/could/can), 

e.g., “May I sit here?” Might lean slightly more towards doubt. For most answers, either one works fine when you are expressing possibility and probability.

Should and Ought To (Advice)

Should and ought to are your main tools for giving advice and recommendations (should/ought to).

• The government should invest more in public transport.
• Students ought to read every day.

These two are gold in Writing Task 2 when you suggest solutions.

Must and Have To (Obligation)

For obligation and necessity (must/have to), reach for must and have to. Must often feel stronger and more personal. Have to point to an outside rule.

• You must finish the essay in 40 minutes.
• Candidates have to show ID at the test centre.

Past Modals

To get high marks, learn from the modal verbs in the past (could have, should have, might have, must have). It will help you speak about past events in a more complicated way.

• The plan failed. They should have prepared better.
• He’s late. He might have missed the bus.

This will demonstrate good control over modality, and it will help you move closer to modal verbs IELTS band 8 response.

Tips for Using Modal Verbs in IELTS

Knowing the words is one thing. Using them with control is what raises your band. Here is how to use modal verbs in IELTS Speaking Part 2 and Part 3, and how to apply modal verbs to improve IELTS Writing Task 2.

• Match the modal to your certainty. If you are sure, use “will” or “must.” If you are unsure, use “may,” “might,” or “could.” Mixing these correctly shows real degrees of certainty, which examiners notice straight away.
• Use them for opinions in essays. Strong, fixed claims sound risky. Softer claims sound mature. That is why modal verbs used to express one’s opinion in an IELTS essay perform so well. “Public transportation should be free” sounds much better than “Public transport must always be free for all.”
• Stay polite in Speaking. Open requests and soft disagreements with could and may. These polite modal verbs for IELTS speaking make your tone warm and natural.
• Do not overuse them. Putting a modal in every sentence sounds odd. That is one or two per idea; that is enough. It is one of the most common mistakes with modal verbs in IELTS, and the correction of this mistake alone will make you fluent.
