[VividJailbird]

Hi, teachers: I wonder what are the exact meaning of and the differences betweeen the following compound nouns?

xxx-to-be
xxx-wanna-be
xxx-would-be

For example:

He is a presindent-to-be
He is a president-wanna-be
He is a president-would-be

What are the differences?? Thanks:)

President to be = president-elect, he will be the next president.
President wannabe = acts like he wishes he could be president, but couldn't possibly be.
Presidential would-be = wishes to be, could be.
