hmmm in that case i will choose as one of my favorite greek words:

Φιλότιμο

I really like that word because there is no actual translation in English! You can say it with an English pronunciation as Filotimobut both i are read as e.

There isn't a singe meaning in that word and many times the tourist might have heard it as a "Greek Filotimo". the meanings varies per situation and phrase and ti can mean proud as a person,generous,kind,that you do your job with humility while at the same time try to help others, that you show hospitality towards others like tourists

So as you can see it's like a "box" that contains all the good words :P

And as an annoying world:

Παίζω

In English it is the world play. When we were kids the world play meant insta joy for me but later on it took a different turn. An example was that when i played that required to be on a team i usually saw in chat phrases like "how you play like this stupid" etc etc not only at me but generally and ofc it's wasn't games that we play for fun but competitive. (in most people's minds)

Also every time i am in the gym and someone wanna do an exercise with the dumbbells i have or machine i am (and not just me it's generic) he will come and say "you play here" :P
