I don't intend for him to be a Greek expert or anything like that. Just familiarize him with the alphabet, some basic words, and an expectation that he can go on to learn more, if he chooses to do so when he gets to college. I think that if we go slowly over the next 6-7 yrs he will probably feel comfortable in a college classroom setting of intro Greek.
Hehehe, then he'll be just fine. If it's just memorising easy vocab and learning the alphabet, well the earlier the better!
I started with Hebrew when I was...hm...10.
This is a suitable age for learning ANY language.
Well... I have no idea how difficult Hebrew really is, but I'm guessing it's very hard. Now I started Latin when I was 10 and I thought it was easy at first - until we hit the Dative at which point my brain sort of started to protest and finally gave up when shorty afterwards the Ablative was introduced and I didn't grasp what adverbials were either. I had no concept of what I was learning, I was just learning it and I just can't see how one can learn ancient Greek without a basic understanding of what a language is, which is something normal 10 year old don't have (especially if their mother tongue is English, that'll make understanding inflective languages intuitively nearly impossible I should think). Some in my class did have that understanding, but I'm afraid I didn't

. That's why I had some reservations about this talk of a 10 year old learning ancient Greek, but as long as it's a slow course there should be little trouble. I just don't think most 10 year old can comprehend ancient Greek syntax and grammar.
