What is a cool way to say “friends” or “group of friends” or “small circle” in other ways or languages?

Parea παρέα in Greek. Cool because it’s the only word in Greek with an Iberian origin. It comes from either Ladino parea or Catalan parella, cognate with Spanish pareja.

The Catalan derivation is probably too good to be true: it refers to the Catalan Company, mercenaries who ran bits of Greece (including Athens) in the 14th century. The parea is a social group of people who hang out together, including having coffee or entertainment together; it would be cute to derive the word from marauding bands of mercenaries, terrorising the countryside of Attica.
