kaiser

n. German emperor; Austrian emperor

Kaiser is the German title meaning "Emperor", with Kaiserin being the female equivalent, "Empress". In English "the Kaiser" is usually reserved for the Emperors of the German Empire. Although the British monarchs styled "Emperor of India" were also called "Kaiser i Hind" in Hindi and Urdu, this word, although similar in form, has no direct relationship with German Kaiser.
