The term originated from the Aramaic. The original Aramaic phrase was used with a Hebrew prefix Alef rather than the latter version with an Ayin. The difference was that the original meaning was "I will create, as I say," while the latter was "What was said has been done." The original Aramaic was either ’gЃ`ѓhЂ ‹`lѓgЃ�hЂ, avda kedavra, which means, "what was said has been done", or ’Ѓ�Ђ ‹ѓЃ�Ђ, avra kedavra, which means "what was said has come to pass" or "caused to perish like the word". Over time, it was corrupted to its current pronunciation with the replacement of both "v" sounds with "b" sounds: b and v can be interchangeable in Aramaic.
