Developed by Velimir Khlebnikov and Alexey Kruchenykh, zaum is a "transrational" language that served as a radical departure from conventional communication.1

The term, which is largely untranslatable, refers to a linguistic experiment intended to move language beyond logical, everyday meanings toward a new form of visionary mysticism. By focusing on the word as pure sound, Khlebnikov and Kruchenykh sought to strip away traditional syntax and semantic constraints, often blending their transrational poetry with a fascination for the "primitive".12

Key examples of this linguistic approach include Kruchenykh’s opera Pobeda nad solncem (1913; "Victory over the Sun") and Khlebnikov’s play Zangezi (1922). These works highlight the movement's broader commitment to the renewal of language, which was often presented in books featuring lithographic illustrations by prominent avant-garde artists.12
