From The Grammarly Blog:
Every language has a unique collection of expressions that are easily understood by fluent speakers but may be hard for those less familiar with the language to parse. These sayings, known as idioms, contain meanings that are not wholly obvious by defining the words individually.
For instance, if you’re absorbed in a book or deep in conversation, and you glance at your watch and realize it’s much later than you thought, you might exclaim, “Time flies!” Of course, time didn’t sprout wings and fly away, but it might feel like it did because it passed so quickly. It’s figurative, it’s visual, and it’s evocative—and it’s probably strange-sounding to those learning the language!
Idioms cover a range of common concepts, such as the workplace, weather, and money. And like the one above, there are also many idioms that express concepts of time.
As we dive into this topic, we’ll define what an idiom is and why idioms can be challenging for language learners. We’ll also list some examples of idioms about time.
What is an idiom about time?
An idiom is a common saying that has meaning in its own culture or language but doesn’t make much sense when broken down into its individual components. Idioms about time can be used in many scenarios, such as to describe the passage of time (“time stands still for no one”), to reference a particular point in time (“at the eleventh hour”), or to describe regular occurrences (“like clockwork”).
It’s not surprising that many of the most popular idioms about time describe time passing too quickly, but ultimately, idioms about time are creative sayings that discuss specific moments or occasions figuratively.
Now that you know all about idioms, it’s high time to divulge some of the most popular idioms about time. Whatever time-related message you’re trying to get across, these idioms will help you make it fun.
