Ancient Greek was one of the best courses I had in university. It changed my view on language and western thinking quite a lot.
My favorite words are
μαθηματικὴ (mathematike): If I remember correctly, it means 1. learning, 2. letter or book and 3. "everything there is to know (for certain)".
χαίρε (chaire): Used as a greeting, literally "be happy!"
Also it is funny that βαίνω (baino) means: I am walking, while "Bein" means leg in German - the amount of Ancient Greek words in German and other languages is ridiculously high.
I think it's more likely that–being an indo-european language–there are frequent cognates between Ancient Greek and other indo-european languages like German.
Here's[0] a massive list of them, and you can see cognates between languages you might not have thought would have them, like Sanskrit, Latin, and Ancient Greek sharing many cognates.
