From French (adjective) + leave (noun), apparently from a French custom, already recorded in the 18th century, of leaving from receptions or other events without formally announcing one’s departure to the host or hostess. Compare Spanish irse a la francesa and Portuguese sair à francesa (“go in the French manner”) but also the otherwise ubiquitous attribution of this behaviour to the English as with French filer à l’anglaise (“leave in the English manner”), Italian filarsela all'inglese, Polish wyjść po angielsku, etc.
French leave (uncountable) (idiomatic, informal, dated)
