There is expressions of language that are true on the basis of their semantic meaning (analytic) and there are expressions of language that are true on the basis of direct observation by the sense organs (empirical).
Analytic truth is essentially entirely comprised of relations between
expressions of language.
Kurt Gödel in his 1944 Russell's mathematical logic gave the following
definition of the "theory of simple types" in a footnote:
By the theory of simple types I mean the doctrine which says that the
objects of thought (or, in another interpretation, the symbolic
expressions) are divided into types, namely: individuals, properties of
individuals, relations between individuals, properties of such
relations, etc. (with a similar hierarchy for extensions), and that
sentences of the form: " a has the property φ ", " b bears the relation
R to c ", etc. are meaningless, if a, b, c, R, φ are not of types
fitting together.

When we try to define a truth predicate on the basis of simple type
theory we have a set of expressions of language that are stipulated
to be true that define the semantic meaning of each type these are
like the axioms of a formal system or the Facts in Prolog.
Then we have expressions of language that can be derived from
expressions built from these defined types these are derived by
applying truth preserving operations, like Prolog Rules.

In the same sort of way that ZFC screened out Russell's
Paradox a correct Boolean Truth(L, x) predicate can screen out the
epistemological antinomy basis of Tarki's Undefinability Theorem.
