What Does “May or May Not” Mean? (Simple and Clear Definition)
At its core, “may or may not” means something is uncertain and could go either way.
It expresses two equal possibilities:
- Something might happen
- Or it might not happen
There is no commitment. No decision. Just uncertainty.
Quick Breakdown
- “May” = something is possible
- “May not” = the opposite is also possible
- Combined → both outcomes are equally likely
Simple Example
- I may or may not go to the gym today.
This means:
- You haven’t decided yet
- Both options are open
Think of It Like a Coin Flip
Imagine flipping a coin:
- Heads → You go
- Tails → You don’t
That’s exactly the feeling this phrase creates.
