When we ask the question: What is a truthmaker? The generic answer is
whatever makes an expression of language true <is> its truthmaker. This
entails that if there is nothing in the universe that makes expression X
true then X lacks a truthmaker and is untrue.
What even is a truthmaker?
I just defined its precise scope.
It is what-so-ever makes an expression of language true.
https://plato.stanford.edu/entries/truthmakers/The cat in your living room makes
"There is a cat in my living room" true.
The definition of arithmetic makes 2 + 3 = 5 true.
X may be untrue because X is false. In that case ~X has a truthmaker.
Now we have the means to unequivocally define truth-bearer. X is a
truth-bearer iff (if and only if) X or ~X has a truthmaker.

What if both or none have a truthmaker?
I already answered for none. When X and ~X have no
truthmaker then X is not a truthbearer.
