A language L is open if it can be extended to a new language L² without changes in the meanings of other expressions; otherwise
But the first-order language L is certainly not reducible to the language L² of syllogisms, since in L we can write down a sentence saying that exactly three elements satisfy
Given two languages L and L², we can compare them by asking whether every class Mod (S), with S a sentence of L, is also a class of the form Mod (S²) where S² is a sentence of L².
If the answer is Yes, we say that L is reducible to L², or that L² is at least as expressive as L.
Recall that a translation from a logic L into a logic L² is a mapping f between the respective sets of formulas which preserves derivability, that is:
We could repeat the recursion clauses for L to produce a full theory of truth for L².
Then for every predicate E (x) of expressions of L defined in L+ one can prove in L+ a general sentence of the form
