In section Model-theoretic conservative extension: I believe the definition is not the intended at the moment. It should read:
:if every model of T_1 can be expanded to a model of T_2 and every model of T_2 restricted to the language of T_1 is a model of T_1.
Otherwise the implication in the next sentence is wrong.

Non-conservative
Should the scope of this article be expanded to include discussion of any supertheory? It seems the roots are already there. Tule-hog (talk) 21:47, 6 January 2025 (UTC)
