`
`Usage Note In the 15th century, the word controller developed the al-
`ternate spelling comptroller as a result of an association between the first
`part of the word, cont, and the etymologically unrelated word count and

`would be the same as for controller, evidence suggests that the spelling
`pronunciations (komp—tr<‘)’lar) and (kompltrifllar) may now be used by
`a majority of speakers. In a recent survey, 43 percent of the Usage Panel
`indicated that they pronounce comptroller like controller, while 57 percent
`pronounce it with mp, as it is spelled, with stress on either the first or
