Here's a breakdown:
* May: A modal verb indicating possibility or permission.
* Be: The verb "to be" in its infinitive form.
Here are some examples:
* "The party may be canceled due to the weather." This implies that the party might be canceled, but it's not definite.
* "She may be at the library." This suggests that there's a chance she's at the library, but you're not sure.
In essence, "may be" indicates that something is possible, but not necessarily guaranteed.
