Language ideology (also known as linguistic ideology or language attitude) is, within anthropology (especially linguistic anthropology), sociolinguistics, and cross-cultural studies, any set of beliefs about languages as they are used in their social worlds. Language ideologies are conceptualizations about languages, speakers, and discursive practices. Like other kinds of ideologies, language ideologies are influenced by political and moral interests, and they are shaped in a cultural setting. When recognized and explored, language ideologies expose how the speakers' linguistic beliefs are linked to the broader social and cultural systems to which they belong, illustrating how the systems beget such beliefs. By doing so, language ideologies link implicit and explicit assumptions about a language or language in general to their social experience as well as their political and economic interests. Applications and approaches Definitions Scholars have noted difficulty in attempting to delimit the scope, meaning, and applications of language ideology. Paul Kroskrity, a linguistic anthropologist, describes language ideology as a "cluster concept, consisting of a number of converging dimensions" with several "partially overlapping but analytically distinguishable layers of significance", and cites that in the existing scholarship on language ideology "there is no particular unity . . . no core literature, and a range of definitions." One of the broadest definitions is offered by Alan Rumsey, who describes language ideologies as "shared bodies of commonsense notions about the nature of language in the world." This definition is seen by Kroskrity as unsatisfactory, however, because "it fails to problematize language ideological variation and therefore promotes an overly homogeneous view of language ideologies within a cultural group." Emphasizing the role of speakers' awareness in influencing language structure, Michael Silverstein defines linguistic ideologies as "sets of beliefs about language articulated by users as a rationalization or justification of perceived language structure and use." Definitions that place greater emphasis on sociocultural factors include Shirley Heath's characterization of language ideologies as "self-evident ideas and objectives a group holds concerning roles of language in the social experiences of members as they contribute to the expression of the group", as well as Judith Irvine's definition of the concept as "the cultural system of ideas about social and linguistic relationships, together with their loading of moral and political interests." Critical vs. neutral approaches The basic division in studies of language ideology is between neutral and critical approaches to ideology. In neutral approaches to language ideology, beliefs or ideas about a language are
