22 Common Idioms & their Proper Usages in IELTS Speaking Section (Part 1/5)

Use Idiomatic Language naturally and accurately in the IELTS Speaking Test

The correct use of idioms in English conversations is the way to distinguish native English speakers from those that learn English as a foreign language.  In the IELTS speaking test, using idioms can really help boost your IELTS score, if used properly. Nevertheless, it can also lower your score, if you can’t use them correctly. What we are trying to do in this lesson is to show you how idioms can be made the most of in the Speaking Test.

Idiom – A group of words (or a single word) which have a meaning that is not understood by combining the standard definitions of the individual words (though that meaning may sometimes be inferred).

Idioms are a style or form of (often artistic) expression, characteristic of a particular language, group, subculture, school of thought, generation, or medium (for example, movies and television).

To master idioms really requires to understand them intellectually (perhaps by first reading) and also to hear them used properly by native speakers (or near native speakers) of English.

Idioms can convey that the current situation being described has a resemblance with past history, and in that sense they may be similar to analogies or metaphors. Learning some key idioms and their usages can help your score in IELTS writing and speaking tasks. It is suggested you not use about 2 idioms in an essay with 250 words.  However, this is a very difficult statement to make with authority, as some idioms are used so frequently that we do not recognize them as idioms, so they are not likely counted as such by an examiner.  You probably already know many of these most common idioms yourself, and also not realize they are idioms.  An idiom may be so commonly used that it just seems like a second definition to you and the native speaker.

Do not try to use an idiom in an IELTS task unless you understand it and can use it properly. This is easier when writing an idiom than when speaking it. If using it in the IELTS speaking test, you should be able to use it with the proper inflection (pitch, tone, modulation, emphasis).  It is important to think of the context of to whom or what the idiom is directed towards.

In this lesson, we are trying to focus on idioms that are more commonly used in business or academic contexts, and would therefore be more appropriate for an IELTS task. When we list an idiom with a W, it means we feel it is formal enough to use in your writing tasks.  All the idioms in our list can be used on the speaking tasks, but if they do not have the W, we consider them a bit less formal and do not necessarily recommend them for your writing task.
