The office, position, or authority of a chancellor; alternatively, the period during which someone serves as chancellor.
From chancellor + -ate (Latin suffix -atus meaning office or position, also used for kingdoms and positions of authority). Similar formations include 'professorate' and 'magistrate'.
The suffix '-ate' (like in 'magistrate' or 'doctorate') is one of English's most powerful position-markers—adding it to any authority figure instantly makes the word sound official and bureaucratic, which is precisely why governments love using it.
