Actually, "AbraKadabra" is the Germanization of the (Anglicized) Aramaic phrase "Ahbra Kedahbra" which translates to "I will create as I speak".

Reference to it appears in an obscure Roman poem written by a physician to an emperor in which he suggests that the emperor wear a medallion bearing the phrase in the shape of a triangle:

A - B - R - A - C - A - D - A - B - R - A

A - B - R - A - C - A - D - A - B - R

A - B - R - A - C - A - D - A - B

A - B - R - A - C - A - D - A

A - B - R - A - C - A - D

A - B - R - A - C - A

A - B - R - A - C

A - B - R - A

A - B - R

A - B

A

Or something like that.
