Portmanteau
port-man-TOW
This neologizing figure mashes up two words to create a single new word. The term comes from Lewis Carroll, whose 1871 novel Through the Looking Glass stars a word-coining Humpty-Dumpty.
The portmanteau is especially useful when you’re describing a novel situation or a new political issue. You can stick standard suffixes onto existing words to make new ones: -asize or –gate or –tron. But the more clever will marry two standalone words. You’re creating figurative nuptials for neologisms: neoluptials, as it were. Or nuptialisms.
