I live in Ireland and although English is the official language, in some areas of the country people speak Irish as their first language. I used to think it was pointless to learn Irish as nobody else speaks it but thats precisely the reason I think it would be fairly cool to speak Irish. If all Irish people spoke it then we'd speak a language only we understand. We'd speak English too of course. There are Irish culture organisations trying to encourage people to learn Irish and all that but I honestly can't see normal people learning the language well enough to speak it. Would you say if the government intended on making Irish the official language they could bring it back by enforcing it?
