I suspect there will now be a criminal investigation into manslaughter charges against the management. There was a lot of concerning evidence around your point during the trial but it is a process. The innaction that facilitated these murders sound like an absolute shambles.
It’s easy. W is a vowel in Welsh. It sounds similar to ö in German and it can be modified as ŵ to elongate the sound such as in the word dŵr which means water.
Wrwgwai or Wcrain (for example) are the natural way to spell those countries using the Welsh alphabet. Its a highly phonetic language believe it or not.
