portmanteau

First of all, I'm not even sure "portmanteau" is the right word and I certainly can't pronounce it. But since "I read it on the internet once", it must be true. According to the wiktionary it's the combining of two words to make one.  A "Frankenword". Skirt + Shorts = a "skort" (or is it a pair of skorts?). Scrooge + Grinch = A Scrinch.
