Bien Sûr
Definition: of course
This is literally French for “of course,” which isn’t interesting, but I’ve never seen it used in an English context before.
Why I Looked It Up
In Monsters: A Fan's Dilemma, when discussing a little-known Hemingway novel:

The author had made the point earlier that the book is “90 percent about people getting haircuts.”
