I think this cones down to British attitudes in general. We aren’t renowned for our linguistic capabilities. This is probably because most people assume they can speak English when they go abroad, so they don’t need to learn another language.
I feel this attitude reflects on the Welsh language. As someone that lives over the border in Chester and has lived in Barcelona, where they have Catalan as the primary language instead of Spanish, this was an interesting article to read.
More should definitely be done to preserve Welsh. Spain has numerous languages such as Euskara and Aragonese, unfortunately, in the case of Aragonese, it hasn’t been preserved by the local autonomous community, so it might become extinct in the near future.
As long as Welsh is taught in schools, the language will live on. As for the wider British attitude to the language, I doubt that will change in the near future unfortunately, but I hope I’m wrong.
