i've been wondering lately: Is there a term that describes words which are portmanteaus, but where one of the conjoined sub-words doesn't contribute its meaning to the definition of the portmanteau?
i'm thinking here about portmanteaus like "cheesecel" that might get used in a very zoomerish way to mean, "someone who is really into eating cheese" (and obviously not, someone who is celibate regarding cheese). i've always assumed these are playful perversions of the word "incel" (interesting because that word is, itself, a portmanteau: "involuntarily celibate"), but maybe the -cel part is coming from somewhere else i don't know about?
___-gate and ___-core portmanteaus (e.g. "gamergate," "cottagecore") are pretty close to this phenomenon, too. i think in those cases you can at least make a tenuous connection to the definition of both sub-words (e.g., "gamergate is the Watergate of the gaming community" or "cottagecore fans are hardcore about cottage aesthetics"), but they feel a bit more removed to me, possibly because we use them so frequently. ___-pilled also feels like another close example, but maybe not a 100% fit.
what's going on here? any thoughts or existing research on this? are there other examples you can think of?
