Why “jalouse” is a great word
JALOUSE — [Verb] To suspect or deduce something from subtle indications; also, to regard with jealous protectiveness. From Scots jalouse, from Old French jalouser ("to regard with jealousy"). The sense "to be jealous of" arose in the late 17th century as a misunderstanding by southern writers due to similarity to jealousy. Unlike "suspect," which implies a vague, often baseless mistrust, or "envy," which denotes a covetous longing for another's advantages, to jalouse is a precise, watchful calculus—the chill from a turned shoulder in a warm room, the scent of a stranger's cologne lingering where it should not be, the quiet, corrosive warmth of watching a beloved laugh too easily with another. It is the private arithmetic of clues, a form of intelligence indistinguishable from sorrow.
