A portmanteau is a word made by combining the spellings and meanings of two (or more) words or word parts, like spork (spoon & fork), frunk (front & trunk), skort (skirt & short), smog (smoke & fog), motel (motor & hotel), etc. Portmanteaus — the plural form of the word portmanteau can be made by adding s (the English way) or x (the French way) — always make me smile, or the creativity behind them does.
