Quick Answer
The correct spelling is “Time Flies”.
The reason is simple: the verb “fly” changes to “flies” in the third-person singular present tense. Since “time” is singular, we always use flies. Writing flys is grammatically incorrect, even if it looks natural at first glance.
Example:
- Correct: Time flies when you’re having fun.
- Incorrect: Time flys when you’re having fun.
The Origin of “Time Flies”
The phrase “time flies” dates back centuries. It is derived from the Latin proverb “Tempus fugit”, which literally means “time flees.” This expression was used in classical literature to convey the fleeting nature of life.
In English, the idiom first appeared in the 16th century, popularized by writers like Virgil and later Shakespeare. The metaphor compares the swift passage of time to a bird in flight—something that moves too quickly to grasp.
Quote Example:
- “Time flies over us, but leaves its shadow behind.” – Nathaniel Hawthorne
Understanding this origin helps you appreciate why “flies” is the correct verb form—it’s not just a quirky English rule, it reflects a long-standing metaphor in literature.
British English vs American English Spelling
You might wonder if the difference between British and American English changes how the phrase is spelled. The good news? It doesn’t.
Both British and American English use time flies. There is no variant spelling like “time flys” in either form.
Examples from publications:
- British English: The Guardian – “Time flies when you’re busy at work.”
- American English: The New York Times – “Time flies during the holidays.”
So no matter where you are in the world, always stick with “flies.”
Why “Flys” Feels Right (But Isn’t)
Many people instinctively write flys, and that’s understandable. It looks like it should match patterns from nouns ending in “-y” that simply add an s to pluralize, such as boy → boys or toy → toys.
However, in English, verbs ending in “-y” follow a different rule:
- Change y → i before adding -es in third-person singular.
Examples:
- fly → flies
- try → tries
- cry → cries
So even if “flys” looks natural, it’s a grammatical mistake. Remember: when using a verb with a singular subject, always check its conjugation.
Common Mistakes with “Time Flies”
Aside from writing flys, other common mistakes include:
- Using plural verbs with a singular subject: Time fly. ❌
- Confusing with other idioms: Time goes fast. (not wrong, but less idiomatic)
- Spelling “flies” as a noun incorrectly: “I saw time flies.” ❌
Quick Tip: Always check if the word is functioning as a verb. If it is, follow the third-person singular rule.
