To be fair, Greek influences a lot of other languages. I had the thought the other day that if one were to learn Latin and Greek, they could probably do just fine in understanding a majority of other languages in use today since most of them derive so many of their words from those two languages.
Many Greek people do, considering if you want to study anything from law to psychology to journalism, you need to learn latin and ancient Greek (though this one is mandatory in highschool) to pass the university entrance exam
