abracadabra: [16] This magical charm reached English, probably via French, from Greek abrasadabra (the c in the English word arose from a misinterpretation of the c in the original Greek word, which in the Greek alphabet stands for s). It seems to have originated (perhaps in the 3rd century AD) as a cabalistic word of the Basilidians, a Gnostic sect of Alexandria, and was probably based on Abraxas, the name of their supreme deity.

magical formula, 1690s, from Latin (Q. Severus Sammonicus, 2c.), from Late Greek Abraxas, cabalistic or gnostic name for the supreme god, and thus a word of power. It was written out in a triangle shape and worn around the neck to ward off sickness, etc. Another magical word, from a mid-15c. writing, was ananizapta.
