the classification of languages in terms of shared grammatical features (as opposed to shared origin), markedness is (very roughly) a study of how certain forms of grammatical organization are more "optimized" than others, and linguistic universals is the study of the general features of languages in the world. He also influenced Nicolas Ruwet's paradigmatic analysis. Jakobson has also influenced Friedemann Schulz von Thun's four sides model, as well as Michael Silverstein's metapragmatics, Dell Hymes's ethnography of communication and ethnopoetics, the psychoanalysis of Jacques Lacan, and philosophy of Giorgio Agamben. Jakobson's legacy among researchers specializing in Slavics, and especially Slavic linguistics in North America, has been enormous, for example, Olga Yokoyama.
