The word is a variant of "controller". The "cont-" or "count-" part in that word was associated with "compt-", a variant of the verb "count". The term, though criticized by lexicographers such as Henry Watson Fowler,1 is probably retained in part because in official titles it was deemed useful to have the title dissociated from the word and concept "control".2
A variant explanation is that comptroller evolved in the 15th century through a blend of the French compte ("an account") and the Middle English countreroller (someone who checks a copy of a scroll, from the French contreroule "counter-roll, scroll copy"), thus creating a title for a compteroller who specializes in checking financial ledgers.34 This etymology explains why the name is often pronounced identically to "controller" despite the distinct spelling. However, comptroller is sometimes pronounced phonetically by those unaware of the word's origins or who wish specifically to avoid confusion with "controller".5
In business, the comptroller is the person who, independently from the chief financial officer in some countries, oversees accounting, and the implementation and monitoring of internal controls. In countries such as the United States, the United Kingdom, Australia, New Zealand, Israel, and Canada, a comptroller or financial comptroller reports to the CFO in companies that have one.
Businesses typically use the spelling controller,6 while government organizations use comptroller.7
In India, Comptroller is an appointment.
In Mexico, the comptroller, translated as 'contralor', was established in the public administration during the presidency of Miguel de la Madrid, when he created the Secretariat of the General Comptroller of the Federation [es] in 1982. This ministry was renamed as the Secretariat of the Civil Service by president Vicente Fox in 2003. Nevertheless, several states still name as General Comptroller Office their audit and oversight institutions. Namely, Mexico City has the Secretariat of the General Comptroller of Mexico City and Jalisco has the Comptroller General Office of the State of Jalisco.
