When I was in Primary school I can remember learning Greek and Arabic at the same time. We had a lovely Lebanese woman (can't remember her name) who came in once a week. I recall she started us with very basic words and common phrases so that we could easily relate them to their English counterpart. We only did it for a year or two and then she just up and disapeared. Sadly, to this day I can only remember a few Arabic words. My brother started learning Arabic a while back, however I feel it was mostly just listen and repeat.
