Language ideology. From Wikipedia, the free encyclopedia. Language ideology (also referred to as linguistic ideology) is a concept used primarily within the fields of anthropology, sociolinguistics, and cross-cultural studies to characterize any set of beliefs or feelings about languages as used in their social worlds.n neutral approaches to language ideology, speakers’ beliefs or ideas about language are understood as being shaped by the cultural systems in which they are embedded, but no attempt to identify variation within or across these systems is made. Often, a single ideology will be identified in such cases.
