Why Should I Care about Idioms?

Here are two good reasons to think more carefully about idioms.

(Reason 1) Foreigners might not understand your idioms.

It is a well-noted observation that non-native English speakers can "understand the first meaning but not the second."

Essentially, this is a warning that any foreigners among your readers might not understand the meanings of the idioms you use (which makes perfect sense given that idioms by definition don't mean what their words mean).

Here are some examples of how you might tune your words for a foreign audience:
English-speaking EnvironmentOption for a Non-native-speaking Environment
The new project is money for old rope.
Be ready at the drop of a hat.
Such an opportunity is once in a blue moon.
The new project pays us again for our previous work.
Be ready starting from now.
This is a rare opportunity.
Often, context will ensure your non-English speakers follow the conversation (especially as many idioms are fairly obvious analogies). However, bear in mind that using an idiom could throw a spanner in the works.

(Reason 2) Idioms can make your writing more engaging.

Idioms are classified as figurative language (the use of words in an unusual or imaginative manner). Figurative language is typically used to express an idea more clearly or more interestingly.

As a rule, idioms do not help with expressing ideas more clearly, but they can sometimes help to ensure your writing is:
  • Less stuffy (idioms give a sense of informality and familiarity).
  • More succinct (idioms can be less wordy than a non-idiomatic explanation).
