you should learn the alphabet and some small words and when you can study a little a text you have to start learn tha grammars roles. If you want i can help you!

Greek is like every other language... It takes time to learn a language and it is no harder than any other one... I would not recommend just picking up words or phrases like a "touristic guide"... Where there is a good mood, there is a way...

you should learn it's alphabet first then the grammar and the how to make a sentence I think if you start to talk it step by step you won't find it hard :D
