Oh I've got many, many fancy terms in that realm. Been collecting some new ones lately too. Here's a great joke that'll no doubt help you remember "abelian group": What's purple and commutes? An abelian grape! With you on vocab, though in a lot of ways (especially math or maybe physics) knowing definitions is a big part of knowing anything; they are so precisely refined over time that they reflect the underlying well, or at least distill it. I dunno if that makes sense, but it's why I find all tech stuff infuriating to understand. Bunch of random terms, different flavors by manufacturer/developer, NOBODY understands any peace fully anymore, etc. gives me vertigo
