Etymology

Origin of lieu

First recorded in 1250–1300; from Middle French, from Latin locus “place”; replacing Middle English liue, from Old French liu, from Latin; see locus

Explanation

To be in lieu of something is to replace it or substitute for it. A restaurant that's run out of clams might serve French onion soup in lieu of chowder. The word lieu originally comes from the Latin locus, meaning "place," and its meaning has stayed true to its origins ever since. Though it does have a standalone definition, "the position or function formerly held by another," this noun is most commonly encountered in the phrase "in lieu of," which means, basically, "instead of."
