Learning Greek - as daunting as it may sound - is not actually the gargantuan task we expect it to be. A lot of our English language comes from rooted words in Greek; for example, poly, which means many, or colossus, which is, well, colossal. Once you can link these root words to their English counterparts, the language starts to sink in as though you've been speaking it since day one.
It's the same story with Greek characters. Their writing contains most of our familiar alphabetical letters; K, O, M, A, I, and T are all written the same in Greek as they would be in English - as capitals, at least. But, again, if you can begin to see those tiny similarities that link our two languages together, you'll soon be able to read one of the most ancient languages in the world.
Take the letter 'p', for example - The Greek symbol for 'p' is 'π', which most of you mathematicians will recognise as Pi. It's easy to remember the sounds these letters make when you've already been saying it for years in math class. Or, for those more science oriented, the lowercase letter for 'L' in Greek is 'λ'. Ring a bell?
If the idea of learning another form of communication is still daunting to you, just remember - a lot of countries out there teach English as a mandatory, secondary language, and English isn't exactly the prettiest thing to learn. No is pronounced like know and yet lead sounds nothing like lead. Did you read it or have you read it? How can light become lit but fight can't become fit? If teachers have taught, have preachers praught?
It's confusing, mad and utterly silly, and yet we speak it every day and expect every one else to do so too. So what's the harm in at least learning a few words of their language for a change? A simple 'Hello,' ‘Yasas’ a 'Thank-you,' ‘Efharisto’ or a 'Please,' Parakalo’ will suffice, and it'll probably bring about a few smiles too.
