I have been studying koine Greek for awhile. I have recently purchased a couple of modern Greek books, one is "Travel Talk" and another is "Conversational Greek." I have noticed some differences in sounds of letters and differences in some vocabulary words. But I figured right now would be a good time to learn some modern Greek just incase I eventually would like to speak Greek. I figured learning to speak it would be helpful even though the variations takes some memorizing, but it seems to motivate me more with the chance to apply Greek beyond reading, but speaking it.
Has anyone here learned both? Is it worth the effort even if I don't get to use it as much as someone who learns Spanish? I wish I could be able to be around people who speak Greek just for the practice of using it.
