Visiting Greece presented some interesting linguistic challenges.
I live in Montreal, which means I have at least some knowledge of the French language. I am not, by any stretch of the imagination, fluent in said language. Frankly, I'm not even very good. My French, basically, is terrible.
But while my French may be terrible, it is at least there. I'm generally able to ask for directions, order a meal from a menu, read the road signs, and even to some extent carry on a conversation, if I keep my words short and avoid slang. When someone says a word in French, I'll stand a chance of being able to match it up with a series of letters on paper, even if the word is unfamiliar.
