I just recieved a Greek Rosetta Stone program as a gift, but I’m pretty sure it’s modern greek. Should I make the effort to use it and try and learn from it, or should I not even try? How different is Ancient Greek from Modern Greek is my real question, i guess
my understanding is that they are quite different, but someone more knowledgeable can verify.
what are the chances that you could trade it in for a different language?
See if your library has it available to you. I can get (any/many?) of the languages they have online from home for free through my public library. I just didn’t like the program very much (I found it boring and slow) but if you like it you can’t beat free.
If what you are interested is Ancient Greek it would help but it would really prove to be extra effort. There are some major differences between modern and ancient Greek (the further back in time you go the greatest) so while it is helpful I’d suggest you don’t use it right now.
Save it somewhere and once you know ancient Greek well enough it may be amusing to note the differences and similarities and whatnot 
Other than that nahh!
Some of the MAJOR differences (minus ending changes): Say bye bye to the infinitive; What passes for infinitive in MG really doesn’t deserve the name (some don’t even call it so). The AG infinitive has survived in some stock phrases (either from AG or from the Puristic form of modern Greek [Katharevousa] )
Major curbing of the forms and use of the participle especially of the Active voice.
Middle voice (not mood obviously) is gone and so is Optative.
No dative (apart from stock phrases)
No dual number
No third declention really (there is and there isn’t but mostly isn’t 
)
No breathing marks and only oxeia from the accent marks
MAJOR shift in pronunciation (unless you are interested in Koine Greek in which case there IS a shift but not that major)
Many loan words from other languages and complete change of meaning in some.
I think that covers it
In other words, if your native language is Greek learning ancient Greek is easier but if it’s not why not go for the AG from the word go if Modern Greek doesn’t interest you?
Thank you everybody. I don’t think the make an ancient greek version of rosetta stone so I wanted to make sure it wasn’t useful and I want to read Homer and Plato and Aristotle, and any of the extant pre-Socratics so it seems as if it would be useless. Thanks Again
Ouch! Useless? That hurt!
i meant the program
