USAGE
In the normal British pronunciation of lieutenant the first syllable sounds like lef-. In the standard US pronunciation the first syllable， in contrast， rhymes with do. It is difficult to explain where the f in the British pronunciation comes from. Probably， at some point before the 19th century， the u at the end of Old French lieu was read and pronounced as a v, and the v later became an f.
