There's no such thing as just a true formula: usually it's understood
by that we mean an interpreted-as-true formula. As such an interpreted
formula needs to have a meaning. But not the other way around. For
example, if the formula F = (0=0) /\ (0=1) has a meaning, its meaning
is *independent* from whether or not F has any truth value!

For example,
GC has some meaning but whether or not it's true or false (by whatever the
chosen underlying truth definition) is a different matter.

Well this is a technical question of some interest. I was under
the impression that interpreting a formula in a given structure
entailed a truth-value assignment also. Perhaps I am mistaken
on this point. Can you explain how a formula F can be assigned
a meaning (interpreted) without thereby arriving a truth-value
for F? I'm, admittedly, slightly fuzzy on this point.
