When exploring All Time or All-time, you’ll quickly see how a small dash shifts meaning entirely. The hyphen isn’t just a line- it decides whether a man is eating chicken or if you’re dealing with a man-eating chicken. That tiny mark holds surprising power to twist the story into something completely different.
I once confused all time with all-time in an article, and my editor caught it instantly. That missing hyphen stripped the phrase of its intended meaning, leaving it unclear. Once I understood the importance of the correct use, I never made the same error again.
Ignore grammar details, and you risk flattening your writing. For example, an all-time record shows the best performance ever, but without the hyphen, all time sounds dull and unfinished. These marks add precision and give your words the polish they deserve.
Hyphenation Basics
A hyphen (-) connects words to create clarity. It prevents confusion and ensures the reader understands exactly what the writer means.
Think about these two sentences:
- She owns little used cars.
- She owns little-used cars.
The first sentence suggests the cars are small and used. The second says the cars were barely used. That tiny hyphen changes everything.
General Hyphen Rules
- Use a hyphen in compound adjectives before a noun.
Example: a high-speed train, a five-year-old child. - Don’t use a hyphen when the words come after the noun.
Example: The train is high speed, the child is five years old.
The phrase all-time follows this exact pattern.
All Time vs. All-time: What’s the Difference?
The choice depends on how the phrase functions:
- All-time (hyphenated) → works as an adjective modifying a noun.
- All time (no hyphen) → functions as a noun phrase, meaning “the entirety of history.”
Side-by-Side Examples
| Phrase | Correct Usage | Explanation |
| All-time | That was an all-time record. | Acts as an adjective before a noun. |
| All time | He is the greatest athlete of all time. | Works as a noun phrase, not modifying another noun. |
Quick test: Ask yourself, Is it describing another word (adjective)? If yes, hyphenate. If not, leave it open.
When to Use “All-time” (with Hyphen)
Writers reach for all-time when they want to highlight unmatched achievements, records, or rankings.
Examples in Context
- Serena Williams is an all-time great in tennis.
- That movie is my all-time favorite.
- It was the team’s all-time best performance.
Here, the phrase works like a badge of honor. It emphasizes uniqueness, extremes, or historic significance.
Mistakes to Avoid
- Don’t write “He is the best of all-time”. The correct version is “He is the best of all time”.
- Avoid over-hyphenating when the phrase stands alone.
When to Use “All Time” (Without Hyphen)
All time stands tall without a hyphen when it’s a noun phrase. It represents the scope of history.
Examples in Action
- Michael Jordan is considered the greatest basketball player of all time.
- That was the most dramatic upset of all time.
- The novel ranks among the most influential books of all time.
Notice how the phrase isn’t directly modifying a noun. Instead, it completes the idea.
The Role of Context
Hyphenation doesn’t exist in a vacuum. Context decides clarity.
Take this sentence:
- “She made an all time favorite dish.”
Without the hyphen, it reads awkwardly. The phrase “all time favorite” becomes confusing. Add the hyphen- “an all-time favorite dish”– and meaning clicks instantly.
Context guides your choice. If the words come before a noun and describe it, use the hyphen. If they stand independently, skip it.
Adjectives and Hyphenation Keys
Understanding how adjectives function helps avoid mistakes.
- Adjective role: Describes or modifies a noun.
- Noun phrase role: Acts as a subject or object without modifying.
Quick Comparison
- All-time adjective: An all-time great singer (describes “singer”).
- All time noun phrase: She is the greatest singer of all time (not describing directly).
Other compound adjectives behave the same way:
- Full-time job vs. working full time.
- Part-time schedule vs. working part time.
- Long-term plan vs. in the long term.
Examples in Action
Let’s make it practical with side-by-side clarity:
| Incorrect | Correct | Why It’s Wrong |
| He is the best of all-time. | He is the best of all time. | Misused hyphen in noun phrase. |
| That was an all time record. | That was an all-time record. | Needed hyphen before noun. |
| My all time favorite song is here. | My all-time favorite song is here. | Without hyphen, it’s unclear. |
These distinctions aren’t about style- they’re about clarity.
Style Guides and Dictionaries
Major references weigh in consistently:
- Merriam-Webster: Defines all-time as “surpassing all others of all time.”
- Cambridge Dictionary: Lists all-time as an adjective used before nouns.
- AP Stylebook: Advises using the hyphen when the phrase acts as a modifier.
- Chicago Manual of Style: Follows general compound adjective rules- hyphen before a noun, open after.
👉 Bottom line: authoritative guides agree on the usage split.
Common Errors and Misconceptions
Even professional writers slip. Here are frequent mistakes:
- Over-hyphenating: Writing “the best of all-time” (incorrect).
- Under-hyphenating: Writing “an all time favorite” without the hyphen (confusing).
- Mixing styles: Switching between forms inconsistently in the same article.
Tip: Pick a reputable style guide and stick with it for consistency.
Beyond “All-time”: Advanced Hyphenation
“All-time” isn’t alone. English abounds with compound adjectives.
Other “All” Compounds

Each behaves like all-time when placed before a noun.
Hyphenation in Numbers and Ages
- A five-year-old child vs. The child is five years old.
- A twenty-one-gun salute vs. The salute had twenty-one guns.
Prefix Rules
- Hyphen after prefixes ending in the same vowel: co-owner, re-enter.
- Hyphen for clarity: re-sign (sign again) vs resign (quit).
These rules reinforce why hyphenation matters- meaning can flip dramatically.
