As Docent Trubetzkoy taught Sanskrit, but soon turned to Slavic. He was famous of his phonological theory and an early proponent of areal linguistics. His long time interest was the reconstruction of the development from IE to Proto-Slavic and from this to modern languages. In the late 1920s he turned to phonology and the Prague school. Sharply criticized Nazis.
