Abracadabra by Donald Michael Kraig

Some people have tried to associate the word with ancient Jewish mysticism and Kabalism . Typical examples say that it is derived from ab, ben, and ruach acadasch, words that respectively mean father, son, and Holy Spirit. Another supposed source is that it is a variation of the Hebrew abreq ad habra, which means, “hurl your thunderbolts even unto death.” Another version has it meaning “Speak the blessing” from the Hebrew “ha brachah dabarah.” There are a wide variety of other variations and supposed sources for this word.
