- Used to describe a linguistic blend

In then-contemporary English, a portmanteau was a suitcase that opened into two equal sections. The etymology of the word is the French portemanteau, from porter, to carry, and manteau, cloak (from Old French mantel, from Latin mantellum). In modern French, aporte-manteau is a clothes valet, a coat-tree or similar article of furniture for hanging up jackets, hats, umbrellas and the like.
- Compound words, which do not involve the truncation of parts of the stems of the words making them up. For instance, starfish is a compound, not a portmanteau, of star and fish (a hypothetical portmanteau of these words might be stish).
