Zaum are the linguistic experiments in sound symbolism and language creation of Russian-empire Futurist poets such as Velimir Khlebnikov and Aleksei Kruchenykh. Coined by Kruchenykh in 1913, the wordzaum is made up of the Russian prefix :wikt:за|за "beyond, behind" and noun :wikt:ум|ум "the mind, nous" and has been translated as "transreason", "transration" or "beyonsense". According to scholar Gerald Janecek, zaum can be defined as experimental poetic language characterized by indeterminacy in meaning. Kruchenykh, in "Declaration of the Word as Such ", declares zaum "a language which does not have any definite meaning, a transrational language" that "allows for fuller expression" whereas, he maintains, the common language of everyday speech "binds". He further maintained, in "Declaration of Transrational Language ", that zaum "can provide a universal poetic language, born organically, and not artificially, like Esperanto." Examples of zaum include Kruchenykh's poem "Dyr bul shchyl", Kruchenykh's libretto for the Futurist operaVictory over the Sun with music by Mikhail Matyushin and stage design by Kazimir Malevich, and Khlebnikov's so-called "language of the birds", "language of the gods" and "language of the stars". The poetic output is perhaps comparable to that of the contemporary Dadaism but the linguistic theory or metaphysics behind zaum was entirely devoid of the gentle self-irony of that movement and in all seriousness intended to recover the sound symbolism of a lost aboriginal tongue. Exhibiting traits of a Slavic national mysticism, Kruchenykh aimed at recovering the primeval Slavic mother-tongue in particular. In modern times, since 1962 Serge Segay was creating zaum poetry. Rea Nikonova started creating zaum verses probably a bit later, around 1964. Their zaum poetry can be seen e.g. in issues of famous "Transponans" samizdat magazine. In 1990, contemporary avant-garde poet Sergei Biriukov has founded an association of poets called the "Academy of Zaum" in Tambov. The use of Zaum peaked from 1916 to 1920 during World War I. At this time, Zaumism took root as a movement primarily involved in visual arts, literature, poetry, art manifestoes, art theory, theatre, and graphic design, and concentrated its anti war politic through a rejection of the prevailing standards in art through anti-art cultural works. Zaum activities included public gatherings, demonstrations, and publications. The movement influenced later styles, Avant-garde and downtown music movements, and groups including surrealism, nouveau réalisme, Pop Art and Fluxus.
