In Wales we have a choice of Welsh or English language form, question 9 asks
Allwch chi ddeall, siarad, darllen, neu ysgrifennu Cymraeg?
Can you understand, speak, read, or write Welsh?
There are 5 boxes to tick
Understand, Speak, Read, Write, None of the above.
I could fill the form in Welsh and tick "Dim un o'r uchod" (none of the above) The ethic group question asks (in Welsh) if I'm British Irish or Other?
Have fun
