Zaum (Russian: зáумь) 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,^[1] the word zaum is made up of the Russian prefix за “beyond, behind” and noun ум “the mind, nous” and has been translated as “transreason”, “transration” or “beyonsense” (Paul Schmidt).^[2] According to scholar Gerald Janecek, zaum can be defined as experimental poetic language characterized by indeterminacy in meaning.
