Ddylwn i ddim cwyno - I shouldn't complain.

No, really. It is after all a joy to see the Welsh language on groceries.

Cymraeg - Welsh language

Cymreig - Welsh - relating to Wales

So 'Llaeth Cymreig' and 'Caws Cymreig' are both fine, dandy and hyfryd.

But please no more 'Llaeth Cymraeg' - Welsh-speaking milk. No more 'Caws Cymraeg' - Welsh-speaking cheese.

Because they're out there, you know. Have a look in your local supermarket. Or a listen, even.
