What Are Idioms? │ Definition & Examples
An idiom is an expression that uses figurative language to convey a meaning different from the individual words’ literal meaning.
Idioms can either stand on their own as complete phrases/sentences (e.g., “Time flies when you’re having fun”) or as one part of a larger sentence (e.g., “on thin ice”).
An apple a day keeps the doctor away.
I’ll take a rain check on our lunch today as I’m not feeling well.
Why do we use idioms?
Idioms are primarily used to emphasize a point or an idea that we’re trying to communicate. Instead of saying, “Things will get better,” you might say, “It’s always darkest before the dawn.”
Both sentences mean the same thing, but the second option is more engaging because it offers a visual contrast. A reader is more likely to remember the sentiment if sensory words are employed.
Idioms are also used to make our language more interesting and playful. While idioms are often used to emphasize an idea, sometimes it’s just more fun to say “Don’t beat a dead horse” than “Stop talking about the same idea over and over.”
Common idioms in English
There are thousands of idioms in the English language, but some are used more than others and have become a normal part of our day-to-day communication.
Idioms used as part of a sentence
These idioms cannot stand on their own as full sentences; however, they are used within sentences to emphasize a point.
Idiom | Meaning | Example |
---|---|---|

Idioms functioning as a complete sentence
These idioms function as complete sentences on their own. However, they can also be used as a part of a sentence, particularly in compound sentences.
Idiom | Meaning | Example |
---|---|---|
Break a leg | Good luck | Break a leg in your performance tonight. |
Hang in there | Don’t give up | Hang in there; it will get better. |

Idioms vs metaphors
Metaphors are a type of literary device that compares two dissimilar things, typically by using a form of the verb “be” (e.g. “My sister is a ray of sunshine”). Idioms, on the other hand, are more broadly defined as common expressions that use non-literal language to convey a meaning.
As idioms can also be used to make comparisons, idioms and metaphors sometimes overlap. For example, describing something as “a piece of cake” is both a metaphor and an idiom. Some idioms might use implied metaphors that don’t explicitly say that something is something else (e.g., “bite off more than you can chew”).
One of the key distinctions between idioms and metaphors is that idioms are always fixed expressions, while metaphors do not need to be.
You are a chicken for not watching the scary movie.
This is the icing on the cake.
Idioms vs proverbs
Idioms and proverbs are very similar; they both employ figurative language to convey an idea in an oftentimes poetic way.
Proverbs, however, are usually complete sentences that give general life advice.
If you want something done right, you must do it yourself.
You can lead a horse to water, but you can’t make it drink.
Hyperbole vs idioms
A hyperbole is an obvious exaggeration of something, while an idiom is a common phrase that might not be understood at first glance.
While both idioms and hyperbole are used to emphasize a point, a sentence that contains hyperbole is likely to be understood without further explanation (e.g., “My to-do list is a mile long”), while an idiom might not make sense unless you understand the context (e.g., “I’ve bit off more than I can chew”).
Idioms are also popular fixed phrases that everyone uses the same (e.g., “A dime a dozen”). Hyperbole can overlap with idioms (e.g., “It’s raining cats and dogs”), but not all examples of hyperbole are fixed expressions; rather, people can come up with their own ways of exaggerating and using hyperbole (e.g., “My grandma is a thousand years old”).
This new schedule is killing me.
I’ll never sleep again after watching that scary movie.
Aphorisms vs idioms
Idioms employ figurative language to emphasize a point, and aphorisms are short phrases that are used to impart wisdom.
Speak softly and carry a big stick.
All you need is love.
Euphemisms vs idioms
Euphemisms employ figurative language to convey unpleasant ideas with pleasant-sounding language. They are used for more specific purposes, like neutralizing harsh language and making taboo subjects more palatable, whereas idioms are just more creative ways of saying things.
Euphemisms are usually words or phrases and not full sentences. They are often used to avoid using offensive language.
Randy is unique looking. [i.e., Randy is ugly]
Adult beverages will be served at the party. [i.e., the party will have alcohol]
