Abstract This study presents a comprehensive philological, historical-religious, and comparative Semitic analysis of the expression “abracadabra,” one of the most recognizable ritual formulas in the history of Western civilization. Although today primarily associated with stage magic and popular culture, the term originally functioned within a late antique apotropaic and medico-magical context. The earliest securely attested occurrence appears in the Liber Medicinalis of Quintus Serenus Sammonicus, where the formula is written in a progressively diminishing triangular form intended to symbolize the disappearance of disease. The study critically examines the principal theories concerning the origin of the expression, including Aramaic, Hebrew-mystical, and gnostic-magical interpretations. Particular attention is devoted to the Semitic concepts of דבר (davar), שם (šem), and ברא (baraʾ), which together illuminate the broader Near Eastern understanding of language as an active, performative, and ontologically significant force. The analysis demonstrates that “abracadabra” should not be understood merely as a meaningless magical utterance, but rather as a ritual-processual linguistic structure operating simultaneously on phonetic, symbolic, visual, and ontological levels. A new interpretative model is proposed through the concepts of “ritual textual entropy” and “ritual algorithm of reduction,” according to which the gradual disappearance of the written formula symbolically represents the dissolution of illness and chaos. The study further argues that “abracadabra” is best understood not as an isolated magical word, but as a ritual-phonetic palimpsest emerging within the multicultural and multilingual environment of Late Antiquity. The research additionally demonstrates that no direct evidence currently confirms the presence of the formula in the Dead Sea Scrolls, canonical biblical corpora, or classical apocryphal literature, thereby emphasizing the necessity of methodological caution in Semitic etymological reconstruction. Nevertheless, the ritual logic of the formula remains deeply compatible with broader Semitic conceptions concerning the creative and transformative power of speech, naming, and textual action.
