Apologies in advance if this is a duplicate.
For instance, when I say, "I need a Kleenex" and by that I mean "I need a tissue regardless of the brand", is there a term for words like Kleenex in this context?
I could've sworn this word exists, and probably ends in -nym. For the life of me, I can neither recall it nor find it anywhere, including this forum where I did a search for things like synonym, hypernym, brand and trademark.
Other words like this include Band-Aid, Jacuzzi and Chapstick.
Here are some sample sentences:
In the UK, Biro is a _____ that can refer to any ballpoint pen.
or
The _____ windbreaker can mean a lightweight jacket of any brand.
or
(InE) "Bring me some Maggi from the store."
"Do you want Maggi noodles specifically, or did you use Maggi as a _______?"
For the record, I would settle for any word or compound word that fits; it doesn't have to end in -nym. I would prefer a single-word answer.
This article by Business Insider lists more words like this, and says the process is called genericization, but doesn't state a term for such words.
PS - I do not care about the part of speech. For example, I think that the noun Google, when used as a verb, falls under this umbrella. But even if it doesn't, is there a term that covers the other examples I mentioned?
