Any portmanteau in a storm

On July 4, 1865, Alice in Wonderland was first published.

In the book, Humpty Dumpty tells Alice that the word “slithy” in the poem Jabberwocky is a "portmanteau" word – a cross between “slimy” and “lithe.”

He also points out that the word “mimsy” in the same poem is another portmanteau word, a cross between “miserable” and “flimsy.”
