Common IELTS Speaking Idioms

Idiomatic language are sometimes misunderstood. People can perceive them as being lazy or too informal, or suggest a lack of otherwise vocabulary. But this isn't true.

Idioms are a great way to connect to someone who may not share the same language. Idioms show that you actually have a broad understanding of English. Idioms tell us that you understand the nuances of the English language. Idioms showcase your ability to use a more figurative meaning in English. Idioms add colour to your language repertoire.

What is an idiom?

An idiom is a phrase or expression with a non-literal meaning. The idiom represents something else, so if you were to try and break it down by lexis, it wouldn't make sense. Let's say you get an 8 in your IELTS exam, you might then use the idiom, 'I feel on top of the world!'. This idiom represents a feeling of joy and happiness, strongly expressed in 'on top', where the positive emotions are running high and you are figuratively 'on top of the world'.

Why would an examiner be impressed by idiom usage?

Idioms show a naturalness of speech. And this is what the IELTS speaking exam is largely about; sounding fluent and natural. There are many idioms across different cultures and many people grow up with these, and so they sound natural when used in speech. This is why practicing them in context is important so you use them correctly. Let's say you are describing yourself or your friend as someone who reads a lot. The correct idiom to use would be a 'bookworm'. Using this incorrectly as a 'bookbug' or 'bookworms' would be incorrect. And if you used 'bookie', this means something else entirely.

What idioms should I use?

Let's look at some useful idioms. There are hundreds of idioms and by no means should you know that many. But it is useful to have some up your sleeve (can you make out the meaning of this idiom given the context?) So let's look at some together. When practicing, see how well they worked when you listen back to your recording. Was it the right idiom? Did it compliment what you were trying to express? Did it add to or round off an idea?
