hiiii
i want to ask about the difference between ancient and modern greek
in pronounciation grammer?
and if the books that downloaded from textkit is teaches ancient or modern greek?
excuse me i ask for grammer and pronounciation?
All the books here are for ancient Greek. For an introduction to the different ancient Greek dialects and where to start if you are considering ancient Greek, see this post.
If it is modern Greek that interests you, may want to take a look here, where they have a very large and completely free (though slightly dated) course on modern Greek, including text and audio.
solom, the link edonelly used is rather good although out of date in some things. Can you be a bit more specific in what you want? In example why you want to know the differences? Some are subtle some are glaringly obvious you see and getting into details about this matter may not interest you (anyway I am not even sure if that is the right section to discuss such a thing).
If you are interested in modern Greek and not ancient I could direct you to several sites depending on what you want (i.e. learning Greek or just getting some linguistic information)
ok ,IreneY
i want to learn ancient and modern greek
so , i’m asked about the difference between them
and thanks for edonnelly
Hmmm ok let’s start with the basics and we’ll see if you want more
a) Pronounciation. In ancient Greek, roughly speaking, you read what you see in front of you modified sometimes by specific rules. In modern Greek you don’t. The accent mark in modern Greek only shows which syllable should be well.. accented. You have to learn how to pronounce different letters (i.e. I,Y,H, EI, YI, OI all sound like i in ink more or less)
b) No dative in modern Greek
c) No optative
d) different and very specifically used infinitive and participle.
e) Differences (simplification) in conjugation
f) Differences in vocabulary especially when it comes to nominative (e.g. Ανή? becomes Άνδ?ας, Κό?αξ becomes Κό?ακας.
In general, bar pronounciation, knowing one of them (either) will make learning the other much, much easier. Going from Ancient to modern is going from the more complicated to the more simplified (bar pronounciation which, after learning how to is easier than modern [see above]) .
Hope that helps 
I hesitate to give more information since you don’t know either and I may confuse you
Hello all!
Ancient and modern greek is quite the same language. Modern greek is the evolution of ancient greek. A few grammar and syntax differences but the structure is the same. The best way to learn the modern greek language if you have a little experience in ancient greek language is to study not only ancient greek text from a certain classical period (e.g. fifth b.c cent) but to study the greek language by time. What I want to say is it’s good to read Homer to expand your vocabulary, Plato, Thoucydides and Rhetorics to understand the whole structure of greek language but if you really want to learn this language and its evolution(modern greek) you should read texts as Ploutarch, Vyzantine texts, and greek poetry of the dark ages. If it’s hard for you to find them I’d be glad to help you. If you’ve ever came to Greece and you think that the language you’ve heard has nothing to do with the language you study you’re wrong. It’s pretty much the same but the acoustical and writing differences may confuse a student.
Can modern Greeks really read and understand ancient greek? If so, why do you have bilingual editions (ancient greek-modern greek) of classical texts?
tico now that’s a looong explanation!
a) read definitely, same alphabet 
b) Koine with a good high-school education fluently, without one it’ll take some effort and they won’t get everything or misunderstand words whose meaning has changed.
c) Homer and non Attic dialects not without lots of schooling
d) Attic. Well, not fluently no. Not without some studying. However, if someone really knows modern Greek he/she could understand what it is about just as long as he/she knew about the differences (i.e. the use of infinitive). However this is rather theoretical since I have yet to meet someone who knows modern Greek really well and hasn’t studied ancient Greek too.
e) if anyone tells you that the Greek language hasn’t changed after more than two millenia enough for people to need some help to understand its more ancient forms then this someone is probably not thinking logically.
f) All of the above are the reasons why we have editions in both ancient and modern Greek. However I wouldn’t call them ‘bilingual’. You’d need to have studied both to understand why but suffice to say that one is the ancestor of the other. I didn’t always get what my great-grandma referred to but…
This is a rather generic effort to answer this question when people far better educated than I am have written whole books about it.
thanks for all
thanks Ireney ,and that’s enough now
