portmanteaus

A portmanteau word, or portmanteau ( (listen), ) is a blend of words in which parts of multiple words are combined into a new word, as in smog, coined by blending smoke and fog, or motel, from motor and hotel. In linguistics, a portmanteau is a single morph that is analyzed as representing two (or more) underlying morphemes. When portmanteaus shorten established compounds, they can be considered clipped compounds.A portmanteau word is similar to a contraction, but contractions are formed from words that would otherwise appear together in sequence, such as do and not to make don't, whereas a portmanteau is formed by combining two or more existing words that all relate to a single concept. A portmanteau also differs from a compound, which does not involve the truncation of parts of the stems of the blended words. For instance, starfish is a compound, not a portmanteau, of star and fish, as it includes both words in full. If it were called a "stish" or a "starsh", it would be a portmanteau.
