1. [Logic] An (truth-functional) interpretation is an assignment of reference to the symbols of a formal language.


  • The definition of 'interpretation' in mathematical logic was originally provided by Alfred Tarski and latter refined with Robert Vaught. The intent was to provide criteria that a definition of ‘true sentence’ should meet. See
