Does “whatever’s written in that book” work as the appropriate kind of “extensional definition” for this purpose? If so, I agree, that’s what I mean by “using without knowing”. (As I understand it, it’s not the right way of using the term “extensional definition”, since you are not giving examples, you are describing a procedure for interacting with the fact in question.)

It’s sort of subtle.
“Whatever’s written in the book at the location given by this formula: ”
defines a word totally in terms of other words, which I would call intensional.
“Whatever’s written in THAT book, point point”
points at the meaning, what I would call extensional.
