What is zangetsu translated to English?

Zangetsu is Ichigo's sWord in the show Bleach. He may be a sWord, but he has a independent mind of his own. His name also means Moon Cutter. He is also the physical form of ichigo's powers. He can also turn into Ichigo's signature move "getsusgatensho" while using "saigo no getsuga tensho" or "final getsuga tensho" however, this attack removes all traces of Ichigo's reiatsu and turns him back to a human. Ichigo then tries to resurrect his powers with the help of fullbring. (ch.437)
