The confusion between maybe vs may be is common because one space changes the grammar.
Both forms are correct, but they fit different sentences.
Maybe means perhaps.
Maybe I’ll go.
May be means might be.
I may be late.
Do not treat may be as a misspelling of maybe. The two forms express possibility, but they do it in different ways.
Quick Answer
Use maybe when you mean perhaps.
Maybe she forgot.
Maybe we should wait.
Use may be when you mean might be.
She may be tired.
This may be the answer.
They are not the same in grammar. Maybe is usually an adverb. May be is a verb phrase made from may plus be.
Why People Confuse Them
People confuse maybe and may be because they sound alike and both suggest uncertainty.
Compare:
Maybe he is home.
He may be home.
Both sentences express possibility. But the structure is different.
In the first sentence, maybe comments on the whole idea. In the second, may be is part of the verb.
Pronunciation does not decide the spelling. Sentence role does.
