Full Idea
If the definition of the truth predicate is to be finite (Tarski insisted on this), the definition must take advantage of the fact that sentences, though potentially infinite in number, are constructed from a finite vocabulary.
Gist of Idea
The language to define truth needs a finite vocabulary, to make the definition finite
