I’m studying modern Greek, and I’ve had trouble finding good resources for vocabulary. Most vocab lists I find are for ancient or New Testament Greek.
I did find this list of 5,000 words (which appears to be linked to this page at York University, but I can’t otherwise find a way to credit the creator of this list). It’s a pdf, so I parsed it into tab-separated format (using
pdftotext and Python). Enjoy!
