how to pronounce colonel

Colonel [kur-nl], /ˈkɜr nl/, with its medial l pronounced as [r], /r/, illustrates one source for the apparent vagaries of English spelling: divergence between a word's orthographic development and its established pronunciation. In this case, English borrowed from French two variant forms of the same word, one pronounced with medial and final [l], /l/, and a second reflecting dissimilation of the first [l] /l/ to [r]. /r/. After a period of competition, the dissimilated form triumphed in pronunciation, while the spelling colonel became the orthographic standard.
