Origin and Etymology of abat–jour
borrowed from French, literally, “(it) strikes down (abat) the daylight (jour),” from abattre “to strike down” + jour “day, daylight,” going back to Old French jorn, jor, going back to Late Latin diurnum (Latin, “daily ration, daybook”), from neuter of Latin diurnus “daily”
