Abracadabra

Abracadabra is Aramaic phraze meaning I create as I speak

Abracadabra is an incantation used as a magic word in stage magic tricks, and historically was believed to have healing powers when inscribed on an amulet. 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 rather dubious, however, as אברא כדברא in Aramaic is more reasonably translated “I create like the word.” The second lexeme in this supposedly Aramaic phrase must be a noun given the presence of the definite article on the end of the word (it cannot be an infinitive construct, as the infinitive cannot take the definite article). Regardless, this phrase would actually be pronounced ebra kidbara, which is clearly different from abracadabra. However, languages in the Middle East are not always hard and fast with the assignment of vowels, and abracadabra is similar enough to ebra kidebra, given the tendency of vowels to shift. A vowel shift is especially likely when a borrowed word or phrase is anglicised. 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 worshipped 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), nor does he account for the final five letters (i.e., -dabra) in the lexeme.
