Origin and History of Portmanteau

The word "portmanteau" comes from French, meaning a suitcase with two compartments. In language, Lewis Carroll used it in "Through the Looking-Glass" when describing blended words like "slithy" and "chortle." Today, portmanteaus are found in modern English everywhere.

Rules for Portmanteau Word Formation

The sounds must blend smoothly. The meaning must mix ideas from both source words. Not every blend becomes popular or correct—easy pronunciation helps!
