Understanding “May or May Not”

At its core, “may or may not” expresses uncertainty or possibility. It indicates that something could happen, but there is no guarantee either way.

For example:

• She may or may not attend the meeting.
  This means she could attend, but she also might not. It doesn’t confirm either outcome.

Difference Between Certainty and Possibility

English has multiple ways to express uncertainty, and understanding the nuance matters:

Phrase	Meaning	Example
May	Possibility	He may arrive late.
Might	Slight possibility	She might take the train.
May or May Not	Equal chance of happening or not happening	They may or may not come to the party.

Notice how “may or may not” conveys true neutrality—it doesn’t lean toward yes or no.
