saloon: [18] Saloon is part of a widespread western European family of words for ‘large room’. They go back to a prehistoric Germanic *salaz, ancestor of German saal. This was borrowed into Vulgar Latin as *sala, whose descendants include French salle and Italian sala. A derivative of this, denoting ‘large size’, was salone, which was borrowed into French as salon. English acquired this at the beginning of the 18th century in two forms: the original salon and the anglicized saloon. [saloon etymology, saloon origin, 英语词源]
