What is an idiom?
Simple answer: What is an idiom? An idiom is a phrase or expression where the meaning of the phrase is not apparent from the words in the phrase. I.e. the literal meaning of the words in the phrase is not the same as the phrase as a whole.
Advanced answer: An idiom is a phrase or expression using figurative language. An idiom’s meaning is not necessarily linked to the words contained in the phrase, but rather, due to its common use over time, has taken on its own meaning as a stand-alone phrase. Some idioms remain close to the literal meaning of the phrase, but become a commonly used expression in a certain circumstance. Often, idioms originate from an original, literal phrase related to a common circumstance – e.g. bite the bullet – but which may be a more unusual or unlikely circumstance today. ‘Bite the bullet’ remains a popular phrase and is now used in a broader range of circumstances than its archaic origins. In other examples, the origin of the phrase was deliberately figurative – such as ‘break a leg’. In this case, the idiom was created to avoid the superstition of giving bad luck to an actor.
What is figurative language?
Literal language is the direct translation, the exact meaning of the words used. E.g. Fred sat down. This ‘literally’ means that Fred. Sat. Down.
Figurative language such as idioms, metaphors and similes, is the use of words and ideas to make a point or suggest a meaning that is different or goes beyond, that of the exact (or literal) meaning of the words used. Figurative language, uses ‘figures of speech’ to give colour to the point that the speaker or writer is trying to make, often trying to create an image in the mind of the listener.
What is the difference between an idiom, a metaphor and a simile?
Idioms, metaphors and similes are all types of figurative language. There are a number of other types of figurative language which we won’t go into here but it’s reasonable to say that whenever your language goes beyond the literal meaning of the words used it is in the realm of figurative.
- A simile is used to compare two things that have a similar quality. Similes usually use ‘like’ or ‘as’ to create the comparison. E.g. She was as white as a sheet, or, the lake was like a mirror.
- A metaphor is a statement that compares two very different things in order to give the object additional qualities. Unlike a simile, a metaphor doesn’t directly compare things using ‘as’ or ‘like’. E.g. My boss is a dragon; her boyfriend is a toad.
- An idiom is different to a simile and a metaphor in that it is not used to compare things, but rather to describe a situation
Why are idioms important for ESL learners?
If you are an English as a Second Language learner, idioms are a more advanced part of the language which are important to master if you are looking to use English at a higher level and sound confident and natural in your communication.
It is often said that idioms are necessary to sound like a native speaker. While that is true in part, they are not essential to necessarily use, but certainly, they are important to be familiar with as native English speakers use them regularly.
We have already seen, as a part of figurative language, idioms are difficult to understand without already knowing what they mean. Therefore, even if you don’t use them, you should try to get familiar with them to aid your listening and conversation skills.
If you want to learn to speak English fluently, idioms are important.
Are idioms formal or informal?
Neither. Idioms are a normal part of language and can be used in any situation. Some idioms are certainly inappropriate for some situations, however, business is full of idioms e.g. ‘raise the bar’, ‘get ahead of the curve’, etc.
How do you use idioms properly?
For ESL students, using idioms properly is the biggest challenge. If you use an idiom that is not very common or is delivered incorrectly, it can sound forced and unnatural. As an ESL speaker, your goal should be to speak in a clear and confident way that makes the listener listen to WHAT you are saying rather than HOW you are saying it.
Have you ever been engrossed in a film and then suddenly you are snapped out of it thinking ‘hang on, that’s not right’. Well using an idiom badly will do the same thing with a listener. Therefore, work out how to use simple, common idioms with fluency and grace. We’ve included our favourite 10 common idiom examples below.
How many idioms are there?
Wikipedia suggests that there are over 25,000 idiomatic expressions in the English language. It’s worth noting, however, that some idioms are regional and these idioms would only be useful to the areas where they are common. Like normal vocabulary, idioms can go out of date or become less culturally appropriate. Therefore, our earlier advice for English language students holds true. Learn a few idioms really well, rather than lots badly.
