Since generations logicians have called sentences
which you clumsily call "not a truth-bearer",
simple called "undecidable" sentences.

A theory is incomplete, if it has undecidable
sentences. There is a small difference between
unprovable and undecidable.

An unprovable senetence A is only a sentence with:

~True(L, A).

An undecidable sentence A is a sentence with:

~True(L, A) & ~True(L, ~A)

Meaning the sentence itself and its complement
are both unprovable.
