Consider every woman loves a man. This could mean:
i.e. ∃X: man(X) ∧ ∀Y (woman(Y) ⇒ loves(Y, X))
(in other words, there is a particular man and every woman loves him)
... or else it could mean:
i.e. ∀Y woman(Y) ∃X: (man(X) ∧ loves(Y, X))
In other words, a possibly different man for every woman (in this case the man is the woman's father).
