Origin of word"abra kadabra"
Answers
The word may have its origin in the Aramaic language, but numerous conflicting folk etymologies are associated with it.
The word Abracadabra may derive from an Aramaic phrase meaning "I create as I speak."This etymology is dubious, however, as אברא כדברא in Aramaic is more reasonably translated "I create like the word." In the Hebrew language, the phrase translates more accurately as "it came to pass as it was spoken."
Abracadabra may comprise the abbreviated forms of the Hebrew words Ab (Father), Ben (Son) and Ruach A Cadsch (Holy Spirit), though an alternative derivation relates the word to Abraxas, a god with snakes for feet who was worshiped in Alexandria in pre-Christian times.
David Pickering's description of the word as an abbreviation from Hebrew is also a false etymology—as he apparently here means Aramaic (בר is Aramaic for "son", it is בן in Hebrew, although בר is an honorific form), nor does he account for the final five letters (i.e., -dabra) in the lexeme.
The first known mention of the word was in the third century AD in a book called Liber Medicinalis (sometimes known as De Medicina Praecepta Saluberrima) by Quintus Serenus Sammonicus,
