I’m currently a second year student at the University of Wales, Aberystwyth. Although I don’t speak Welsh, I was born here (but moved to England at a very young age) many of my relations are native Welsh speakers.
I’m sure I must have something constructive to add, but a lot has been said already, here are a couple of interesting titbits.
S4C, the Welsh language TV channel, is the most subsidised television channel in the world. All road signs, and public information signs are Bi-lingual (with the welsh first) as well as many place names. Signs painted directly on to the road (for example Slow) are in Welsh. All the literature at University is bi-lingual, and several welsh language course are offered (for example Dram which I study, is available both as an English and Welsh degree) in exams the instructions given by the staff are given in both Welsh and English. All the staff are advised to learn Welsh as another language.
There is a significant amount of North-South Racism, (that is against welsh natives from the other end of the country) the Welsh language is significantly different in North Wales to that in South Wales.
Regarding the switching to Welsh, I have never experienced this and have drunk in the pubs you’re not supposed to into unless you speak Welsh, but on the other hand a friend of mine who is a non-Welsh speaker ended up in the Welsh speaking halls of residence by mistake, and was ignored for the entire year.
Also if you know any bi-lingual (any language) speakers, listen to them having with another bi-lingual speaker, they often switch between languages without realising it at all.
Wales is often considered a country is crisis, that is a crisis of identity, working within the theatre I get to see some indication of this, it’s difficult to summarise but theatre here, (including Welsh language theatre) seems to be reasonably healthy at the moment.
There is some nationalism still around, but while I feel that a cultural identity is a good things, I’m sure that standing at the border with big point sticks can’t be good at all.
I’ve rambled really, if there’s anything specific you want to know, I’m sure I or the others will try and answer it.
