Epiousios
As a Greek who's lived abroad and has taken a jab at a bunch of different languages, I always talked to my friends about how easy it is to understand most Greek words even if I've never heard of them before. Yes, there are a lot of etymological roots that change + exceptions but it is a lot simpler to make out (or make up) words than it is with other languages. Especially, ones that have a complex genealogical history like English. For example, chicken, turkey, poultry, bird are all different in English but in Greek you can find the word for bird in all of them (κοτόπουλο, γαλοπούλα, πουλερικά, πουλί). Btw this is also why I think that Greek is a relatively easy language to learn (but there isn't much material to get people started unfortunately :( )<p>TIL that a word I've been hearing and saying since I was 5 does not mean what I thought it meant and it's still baffling me haha made my day really
