Portmanteau

A portmanteau (i/pɔrtˈmæntoʊ/, /ˌpɔrtmænˈtoʊ/; plural portmanteaux or portmanteaus) or portmanteau word is a combination of two (or more) words or morphemes, and their definitions, into one new word. The English is derived from French portemanteau (portmanteau luggage which has two compartments). A portmanteau word fuses both the sounds and the meanings of its components, as in smog, coined by blending smoke and fog, or the term "wurly" to describe hair that is both wavy and curly. In linguistics, a portmanteau is defined as a single morph which represents two or more morphemes.
