Portmanteau (luggage)
Type of leather travelling bag
From Wikipedia, the free encyclopedia
A portmanteau is a piece of luggage, usually made of leather and opening into two equal parts. Some are large, upright, and hinged at the back and enable hanging up clothes in one half,[1] while others are much smaller bags (such as Gladstone bags) with two equally sized compartments.[2]


The word derives from the French word portemanteau (from porter, "to carry", and manteau, "coat") which nowadays means a coat rack but was in the past also used to refer to a traveling case or bag for clothes.[3][4] By metaphorical extension, following Lewis Carroll's use of portmanteau in Through the Looking-Glass, the word now also names a type of word composed of two merged parts.[5][6]
Portmanteau mail bag

In the 1700s, the term also described a mail bag.[7] This continued into the 1800s for bags used by the United States Postal Service.[8][9] An 1823 resolution in Congress further stated that "locks... will be placed on the portmanteaus containing the principal mails [which] can only be opened... at the distributing offices."[10]
