probably a lot of these in there: words with an edit distance of 1 from a real word where the "fake word" is too close to be interesting. one I found was "subdivison", which I thought just said "subdivision": https://l.thisworddoesnotexist.com/uYDQ

also "jocky", which sure doesn't literally exist but it's hard to argue that it's meaningfully dissimilar to "jockey": (https://l.thisworddoesnotexist.com/J8RS) anyway this is pretty fun all the same.

in another episode of "algorithms doing a racism" I landed "cacadian", whose definition is "a black person" (we're ok so far) but the example sentence was "I'm the worst cacadian up here", which... https://l.thisworddoesnotexist.com/iTVc

"nondestructable" (https://l.thisworddoesnotexist.com/bBD3) is given the definition "of negligible quality or severity" but definitely gets used (spelled nondestructible) to mean "a thing that can't be destroyed" when talking about games with destructible environments

"downcycled" is definitely a word (https://l.thisworddoesnotexist.com/JRd8)

innocuous ones I liked include unclary (https://l.thisworddoesnotexist.com/ibNn), saucescent (https://l.thisworddoesnotexist.com/4VTH), nonboreal (https://l.thisworddoesnotexist.com/eCqw).

I think it's pretty fun.
