Linguistic ecology
Open-knowledge reference entry

Linguistic ecology or language ecology is the study of how languages interact with each other and the places they are spoken in, and frequently argues for the preservation of endangered languages as an analogy of the preservation of biological species.
The term was first used in an article on the "language situation" in Arizona (Voegelin, Voegelin and Schutz, 1967). It was taken up by Einar Haugen, who pioneered a form of linguistics which used the metaphor of an ecosystem to describe the relationships among the diverse forms of language found in the world, and the groups of people who speak them.
Description
Linguistic ecology is represented by the journal Language Ecology, which describes the field as follows:
The ecology of language is a framework for the study of language as conceptualised primarily in Einar Haugen's 1971/72 work, where he defines language ecology as "the study of interactions between any given language and its environment". It was a reaction to the abstract notion of language – as a monolithic, decontextualised, static entity – propagated by Chomsky, and it was conceived as a broad and interdisciplinary framework. In his use of 'ecology' as a metaphor from biology in linguistics, Haugen formulated ten questions which together comprehensively address factors pertaining to the positioning of languages in their environment. Each of these relates to a traditional sub-field of the study of language – encompassing historical linguistics, linguistic demography, sociolinguistics, contact, variation, philology, planning and policy, politics of language, ethnolinguistics, and typology – and each of them intersects with one or more of the other sub-fields. Taken together, answering some or all of these questions is part of the enterprise of the ecology of language. Since then the notion of ecology in linguistics has evolved to address matters of social, educational, historical and developmental nature. With the development of ecology as a special branch of biology, and issues of the 20th and 21st centuries such as migration, hybridity and marginalisation coming to the fore, the notion of language ecology plays an important part in addressing broad issues of language and societal change, endangerment, human rights, as well as more theoretical questions of classification and perceptions of languages, as envisaged in Haugen's work.
This brief starts where responsible research should: with the source description of “Linguistic ecology” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q28407957. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1967 and 1971.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
