Know the difference between modern Greek and ancient Greek. The latter is useful if you plan to study classical literature at a scholarly level. If you simply want to speak the present-day language, modern Greek is what you need to learn.
Buy or borrow an audio-based Greek language-learning program. Since the alphabet is so different, it is more effective to learn conversational Greek phonetically rather than visually. You will need to listen to audio instruction so that you can start speaking and understanding the language. Visual cues are helpful but not necessary at the beginning.
Find Greek language classes or a Greek tutor, preferably a native speaker. Check colleges or universities for continuing education programs or classes. You may also be able to find Greek language classes online.
Look for TV shows and movies in Greek. For example, if you live in a large metropolitan area (such as New York City or Chicago) you may be able to find news broadcasts or children's shows in Greek. Viewing television or movies in Greek could be a good way to pick up the basics of the spoken language.
Focus on phrases you will use in practical, everyday situations: "I would like a bottle of water, please," "Which way to the Parthenon?" and other similar phrases. As you use these phrases, they will become part of your natural vocabulary. Think about phrases you use frequently in English and learn the Greek equivalents.
Find Greek cultural activities in your area after you've learned basic conversational Greek. Seek out opportunities to speak the language whenever possible --- even in a Greek restaurant.
