Definition of the word object language

The term "object language" originates from the field of logic, particularly in mathematical logic and philosophy of mathematics. In logic, an object language refers to a language that is interpreted within a specific domain or system of objects. It is called an "object language" because it is the language that deals directly with objects, as opposed to the metalanguage, which is the language used to describe or discuss the object language. For example, in mathematics, an object language could be the formulas and symbols used to represent arithmetic operations, while the metalanguage could be English or some other language used to explain the meanings or rules of the object language. The concept of an object language is important in understanding how logic deals with formal systems and how these systems can be used to reason about real-world situations or objects.
