anywhere else or just London?
Sorry I forgot to put that he is black and his school is a mix of white, asian, chinese. But he's been sent hom with a dictionary with Tamil words in it

Not aware of Tamil being taught here in East Yorkshire but the primary school age children are learning Polish.
Famillies of primary age kids were invited to the local Community Centre leading up to last Christmas & Easter of this year, so that they could learn how Christian Polish famillies celebrate the festivals plus to learn to speak Polish too.

How do you teach someone to learn something?

they do not teach Tamil in the Northeast

are you of Sri Lankan origin? this may explain why, if not, then no, i havent come across it before

they used to teach french and german when i was at school, perhaps talk to the school and have him taken out of that class, after all what is the point, the language of england is english, business languages are mainly english, french and japanese, what is the point of learing tamil? i cant see it personally.
