Object language

semantics

Object language, in semantics and logic, the ordinary language used to talk about things or objects in the world—as contrasted with metalanguage, an artificial language used by linguists and others to analyze or describe the sentences or elements of object language itself. The concept was developed by such 20th-century logical positivists as Polish-American Alfred Tarski and German-American Rudolf Carnap.
