Pronunciation

The British pronunciation of the French word "lieutenant" (as "lef-tenant") is the official pronunciation as used by the Canadian Armed Forces, but the American pronunciation of "loo-tenant" (which is closer to the original French pronunciation) is sometimes heard outside of the military.
