Just how did a 19th century French suitcase come to represent a unique category of words?
It was Lewis Carroll that provided the connection. In his children's book Through the Looking Glass, Humpty Dumpty explains that a portmanteau is a word with two meanings packed into one.
In truth, a “portmanteau” is itself a portmanteau!
Its name is derived from combining the French words porter (meaning “to carry") and manteau (meaning “cloak”).
