Using idioms in IELTS to achieve a higher band is both reality and a myth. The difference lies in how naturally you use them in your sentences. Idioms deliver a complex idea in a very simple manner. Using them just for the sake of using makes the sentence look forced and using them too little, somehow disrupts the flow. We are here with all the details about using idioms in IELTS.

What are Idioms?

Idioms are “a group of words established by usage as having a meaning not deducible from those of the individual words (example: over the moon, see the light etc.)”

There are many idioms used in English daily, whether in a business context, in the media and in social conversations between friends. Idioms are used informally most of the time and should therefore not be used in the writing test. Spoken English is normally much less formal than academic written English, so it is fine to use them in the speaking test.

How important are Idioms in IELTS?

This image shows a part of the band descriptors for speaking. The 3 bands are 7, 8 and 9. As you can see, using idioms, even with some inappropriate choices, is typical of a band 7 candidate. By using them skilfully, with only occasional inaccuracies you are likely to get an 8 in this category. Rarely students use them perfectly and those who do, achieves a 9.

It must be remembered that Idioms are like seasonings in a dish. You must add them in moderation, too much of it and you will sound like someone rattling it off a list whereas, too little will make you sound bookish. Balance therefore, is the key.

List of Idioms

You should only use idioms if you have heard how they are used in context and you are 100% sure you are using them in the correct way. This may sound harsh, but it is better than losing marks.

Below are some common idioms that I have heard students use correctly in the IELTS speaking test. If you have never heard any of them before, try to find more examples of how they are used and then practice using them when you are practicing speaking. Also, understanding where they originate from can help you remember them.

If you can, have a native speaker or English teacher listen to you and tell you if you are using them correctly.

Most of these are ways to describe something, someone or how you feel. These tend to be easier to use because you can substitute the description you would normally use for the idiom.
