means A senior official who audits and oversees financial accounts and spending, especially in government or large institutions.

from This word is simply 'controller' — from Old French contreroller, 'to keep a counter-roll,' a duplicate register used to check accounts — that got dressed up by a spelling mistake. Scribes wrongly linked the first syllable to French compte, 'account,' and inserted a 'p' that was never pronounced and didn't belong. The error stuck, giving English a job title with a silent letter as a badge of bureaucratic history.
