Avada Kedavra (the killing curse), is the only incantation in the Harry Potter series that's based not on Greek or Latin words but on words from Hebrew and Aramaic. In Hebrew avada means "I will destroy," and kedavra means "as I will speak," so the killing curse in Hebrew means "I will destroy as I will speak," a fitting translation.
