a new word formed by joining two others and combining their meanings; "`smog' is a blend of `smoke' and `fog'"; "`motel' is a portmanteau word made by combining `motor' and `hotel'"; "`brunch' is a well-known portmanteau"
A portmanteau (plural: portmanteaus or portmanteaux) (IPA pronunciation: ) or blend is a word or morpheme that fuses two or more words or parts of words to give a combined meaning. A folk usage of portmanteau refers to a word that is formed by combining both sounds and meanings from two or more words (e.g. spork or foon from spoon/fork and fork/spoon, respectively; "animatronics" from "animation" and "electronics"; or "blaxploitation" from "black" and "exploitation"). Typically, portmanteau words are neologisms.
A portmanteau (from 16th century French, plural portmanteaux) is a large travelling case made of leather. Originally designed with two sides with the hinge in between, one side to carry (porte) your coats (manteaux) and the other side for other items. The portmanteau could stand on end, so that the coats are hung vertically, and open up like a book to make a pair of mini-closets joined by hinges.
