Time Flies or Time Flys: What This Means in Simple English?
The easiest way to understand time flies or time flys is to learn what the phrase means.
The phrase time flies means time seems to pass very quickly.
People often say this when they are having fun or when they are surprised by how quickly days, months, or years have passed.
For example:
- Time flies when you’re having fun.
- I can’t believe it’s already Friday. Time flies!
- Time flies during the summer holidays.
- Time flies when you’re with friends.
In each sentence, flies is the action word. It tells us what time is doing.
Think of time as if it were a bird flying through the sky. Of course, time cannot really fly, but this expression helps us imagine how quickly it passes.
Why Is “Flies” Correct?
The verb fly changes its spelling when it is used with a singular subject like:
- he
- she
- it
- time
Look at these examples:
- The bird flies.
- She flies to New York every year.
- Time flies.
In each sentence, the subject is singular, so the verb becomes flies.
Why Is “Flys” Wrong?
Many learners think they only need to add -s to the word fly.
That would create:
❌ flys
But English has a spelling rule.
When a verb ends in a consonant followed by y, change the y to i and add -es.
So:
- fly → flies
- try → tries
- carry → carries
- study → studies
- cry → cries
Because of this rule, flys is not the correct verb spelling.
Why People Mix These Words Time Flies or Time Flys?
Many people confuse time flies or time flys because adding -s works for many English verbs.
For example:
- runs
- jumps
- eats
- walks
So learners naturally think:
fly → flys
Unfortunately, this verb follows a different spelling rule.
Another reason is that people often hear the phrase before they see it written.
When someone says,
“Time flies.”
you cannot tell if it is spelled flies or flys.
This causes many spelling mistakes.
Look at these examples.
❌ Time flys when you’re busy.
✅ Time flies when you’re busy.
Another example:
❌ My holiday flys by every year.
✅ My holiday flies by every year.
Once you learn the spelling rule, these mistakes become much easier to avoid.
