In the 1920s, language began to be seen as a social phenomenon, and Russian and Soviet linguists tried to give a sociological explanation to features of language. At the same time, Soviet linguists sought to develop a "Marxist" linguistics, as opposed to the early theories that were viewed as bourgeois. Based on this, linguists focused more on the spoken forms of the language, and devoted more time to the study of non-standard dialects than previous linguists had done.
