All Time vs. All-Time: The Short Answer
Here’s the simple answer.

- All-time is a hyphenated compound adjective that appears before the noun it describes.
For example:
Correct
- Michael Jordan is one of the greatest basketball players of all time.
- She broke the all-time scoring record.

What Does “All Time” Mean?
Definition
All time refers to the entire span of history or every period that has existed up to the present. It emphasizes that something ranks above everything else throughout history.
You’ll almost always see it in the phrase:
- of all time
In this structure, all time acts as part of a prepositional phrase rather than an adjective.
Examples of “All Time”
Here are some common examples.
- The greatest novel of all time.
- The highest-grossing movie of all time.
- She is one of the most influential scientists of all time.
- It remains my favorite vacation of all time.
- That was the funniest speech of all time.
Notice something important.
The phrase comes after the noun in every sentence.
That pattern stays consistent across nearly every type of writing.
When Should You Use “All Time”?
Use all time whenever you’re referring to something across the entire course of history.
Common phrases include:
- Best player of all time
- Greatest invention of all time
- Most successful entrepreneur of all time
- Largest animal of all time
- Favorite book of all time
These expressions compare one person or thing against every comparable example in history.
What Does “All-Time” Mean?
Definition
All-time is a compound adjective.
Compound adjectives combine two or more words to describe a noun. Writers connect these words with a hyphen to show they function together as a single modifier.
Examples include:
- Well-known author
- High-quality product
- Long-term investment
- Full-time employee
- All-time record
The hyphen tells readers that both words belong together.
Examples of “All-Time”
Here are several examples.
- The team set an all-time record.
- She became the all-time leading scorer.
- We reached an all-time high in sales.
- This restaurant remains an all-time favorite.
- It was an all-time classic performance.
- The museum welcomed an all-time attendance record.
Each example places all-time directly before the noun.
Why Writers Use the Hyphen
Without the hyphen, readers may briefly misunderstand the sentence.
Compare these examples.
Correct
- The company reported an all-time high.
Less clear
- The company reported an all time high.
The hyphen immediately tells readers that all-time modifies high.
Although many readers would still understand the second sentence, professional writing follows the hyphenated form because it improves clarity.
The Main Grammar Rule
Fortunately, the rule is easy.
Use “All-Time” Before a Noun
Whenever the phrase describes a noun directly, use the hyphen.
Examples include:
- All-time favorite

Example sentences:
- Lionel Messi became the all-time leading scorer for his national team.
- The stock market reached an all-time high.
- That remains an all-time favorite among readers.
- The museum welcomed an all-time record number of visitors.
Use “All Time” After the Noun
When the phrase follows the noun, leave out the hyphen.
Examples include:
- Greatest of all time
- Best movie of all time
- Most influential speech of all time
- Favorite meal of all time
- Fastest runner of all time
Example sentences:
- Many people consider Shakespeare the greatest playwright of all time.
