All Time or All-Time? Which is Correct?

When you want to describe something as the best, the worst, or the most unforgettable, you might be unsure about whether to use all time or all-time.

All timeis a phrase you can use when you’re talking about the whole history or existence of something. It’s like adding ‘throughout history’ directly to the word you’re modifying.

On the other hand, ‘all-time’ with a hyphen turns into an adjective that means “never seen before” or “better than all others so far.”

All Time or All-Time? Which is Correct?

Both ‘all time’ and ‘all-time’ can be correct, but it depends on how they’re used in a sentence.

You should use ‘all-time’ with a hyphen when it’s an adjective before a noun. For example, in ‘all-time high,’ it shows that whatever you’re referring to is the most remarkable in history.

Meanwhile, ‘all time’ without the hyphen is a phrase that refers to the broadest sense of time. Like in the sentence, “Shakespeare is one of the greatest playwrights of all time.”

So, when you’re deciding between ‘all time’ and ‘all-time,’ consider if you’re talking about a general concept of time or describing something specific.

All Time: Meaning and Usage

‘All time’ is a phrase that means ‘forever’ or ‘throughout history.’ It’s used to talk about a period from the past and into the indefinite future.

Because it acts as a noun phrase, it doesn’t have a hyphen. For instance, you might say, 

  • “This library has been open for all time” 

This means, the library has been open for a very long time and will continue to be. Here, ‘all time’ refers to how long the library has been open, not something about the library itself.

To explain this more, let’s look at another example,

  • “This song has been my favorite for all time” 

It means that this song has always been your favorite and always will be. This gives a feeling of ongoing and permanent love for the song.

Here’s an easy way to check if you’re using it right — if you can put ‘of all time’ after the noun and the sentence still makes sense, then you’ve used ‘all-time’ correctly.

All-Time: Meaning and Usage

All-time works as an adjective, showing that something is the best or most extreme in history until now.

For example, if you say a sports player has broken an ‘all-time record’, you mean they’ve beaten all previous records so far.

Here’s how to use ‘all-time’ in sentences:

  • The film became an all-time bestseller after it sold more copies than any before it.
  • This summer’s temperatures have reached an all-time high, breaking 100 years of weather records.

Remember, ‘all-time’ changes the meaning of nouns, and you need to put it right before the noun it’s changing.

“This song has been my favorite for all time.

“Shakespeare is one of the greatest playwrights of all time.”
