A correspondent of Notes and Queries (July 21, 1877) says that the compound Russian word Nebock-ad-ne-tzar means, There is no god but the czar. Of course this is not the meaning of the Babylonian proper name, but the coincidence is curious. The -ezzar of Nebuchadnezzar means Assyria, and appears in such words as Nabonassar, Bel-ch-azzar, Nebo-pol-assar, Tiglath-Pil-eser, Esar-haden, and so on.
Nabonassar is Nebo-adan-Assur (Nebo prince of Assyria); Nebuchadnezzar is Nebo-chah-adun-Assar (Nebo, royal prince-of Assyria). Nebo was probably an Assyrian god, but it was no unusual thing for kings to assume the names of gods, as Bel-ch-azzar, where Bel = Baal (Baal king-of Assyria.) (See NABO.)
