However discourse combines both language and practice and is not simply a power to name. Barker asserts this dual aspect of discourse: “… discourse is said to ‘unite' language and practice and refers to regulated ways of speaking about a subject through which objects and practices acquire meaning” ( Sage Dictionary ). Moreover, if culture refers to maps of meaning created by ideology, these maps achieve a semblance of stability only through discursive practices or culturally sanctioned and codified rules of ways of constructing and organizing knowledge.
