Portmanteau word

A portmanteau word () is made of other words, or parts of words. It comes from putting two (or more) other words together, like "motel", from "motor" and "hotel".
Origin.
"Portmanteau" originally meant a type of suitcase with two separate parts for storage.
The first use as a word combination appeared in Lewis Carroll's book "Through the Looking-Glass". There Humpty Dumpty explains that some of the unusual words in "Jabberwocky" are other words packed together into one word, as two parts of a portmanteau suitcase are packed together.
Examples.
"Portmanteau" itself is an example, combining the French words for carry (porter) and coat (manteau) into a coat carrier. "Wikipedia" is a portmanteau of wiki (Hawaiian for fast) and encyclopedia.
