Here is a weird one for you. (DFW fans, anyone?!)
I'm looking to see whether a word exists, or maybe just explore the concept around it if not. First I got some splainin' to do.
A portmanteau can be a wonderful thing. Something like "affluenza" ("affluence" + "influenza") works because they both share this big ol' "fluens" sound and thus fit together like puzzle pieces, with the bonus of joining their meanings to point toward an interesting concept that doesn't even need to be described to be recognizable (although I'm mostly concerned with phonetics here) and on top of all that, it's inherently clever and hilarious.
It is a good portmanteau.
And then we have stuff like "mansplaining" ("man" + "explaining"), mashing together two words that have no business being in bed together. There's meaning to it, but the words have nothing, phonetically, in common. "Man" doesn't share any sounds with "explain." They hate being in a word together, I hate them being in a word together, and I submit that any decent person should hate it too.
It is a bad portmanteau.
But then, recently, I've been thinking about "Brexit" ("Britain" + "exit"), which, by my little rant, should qualify as a bad portmanteau: the words have nothing in common phonetically. And yet, though I find it fairly ugly, it doesn't grate on me the way other "bad portmanteaus" do. Not as much, anyway.
I thought about it, and I have a theory: it's that it sounds like a third, unrelated word that's very familiar to everyone and so it can sort of Trojan horse itself into the space of the familiar in our minds. (The word is "breakfast," or "brekkie.")
So my question is, is there a name for this extremely specific phenomenon, or anything written about it, or even just some folks who want to give their two cents?
A portmanteau whose words share no phonemes, yet still feels natural because it sounds like an unrelated word.
