Editing Linguistic relativity (section)

=== Leiden school ===
The [[Leiden school]] is a [[theoretical linguistics|linguistic theory]] that models languages as parasites. Notable proponent [[Frederik Kortlandt]], in a 1985 paper outlining Leiden school theory, advocates for a form of linguistic relativity: "The observation that in all [[Yuman languages]] the word for 'work' is a loan from [[Spanish language|Spanish]] should be a major blow to any current economic theory." In the next paragraph, he quotes directly from Sapir: "Even in the most primitive cultures the strategic word is likely to be more powerful than the direct blow."<ref name="Kortlandt1985">{{cite book |last=Kortlandt |first=Frederik |editor-first1=Ursula |editor-first2=Gerhard |editor-last1=Pieper |editor-last2=Stickel |date=1985 |chapter=A Parasitological View of Non-Constructible Sets |chapter-url=https://www.kortlandt.nl/publications/art067e.pdf |title=Studia linguistica diachronica et synchronica |publisher=De Gruyter Mouton|doi=10.1515/9783110850604|isbn=9783110850604 }}</ref>
