A tiny lesson: Two related dying Gaelic tongues, one in W. Ireland and one in the Scottish islands, are spoken or so I was told. The Welsh tongue, Cymraeg, almost killed by the English but now thriving is similar to Breton and both are very distantly related to Gaelic. All are considered to be Celtic. For more about this visit Llyfrgell Genedlaethol Cymru / National Library of Wales in Aberystwyth. I adore finding ignorance; it gives me a chance to educate.

@@donaldedward4951is there not two different dielectric, north and south Wales also Cornwall and Isle of Man

I wouldn't accuse people of being 'ignorant' if I were you. You're obviously as ignorant yourself and you are arrogant and divisive,. Didn't you listen to the discussion? Welsh was not 'nearly destroyed by 'the English' (as you so divisively call them). Huge numbers of English speaking migrants came into Wales in the 18th and 19th Century (largely into Glamorgan and Monmouthshire) including at least 30,000 English speaking migrants from Ireland and Welsh speakers who'd also migrated there from the Wales countryside chose to join in to fit in with them. The UK would no doubt have preferred English to Welsh but did very little practical to discourage Welsh speaking, even in schools. Most Welsh speaking parents however wanted their children to learn English, so put pressure on schools to make their children to learn it. The Welsh language is NOT thriving. It's compulsory to exhibit it everywhere, and have it on TV since 1982, but the proportion of inhabitants of Wales claiming to be able to speak Welsh has dropped to an all time low of 17.8% in the 2021 census, compared with 19% in 2011, a whopping 37% 100 years ago and at least 60%. In the heavily populated parts of South East Wales, the numbers able to speak Welsh, are as low as 5% and you hardly ever hear it spoken there. You can't force people to learn a language they see no use for. Welsh is not simply 'one of two related Celtic tongues';. Cornish, Scottish Gaelic, Irish, Manx and Welsh belong to the 'Celtic' branch of Indo-European. But English is also Indo European. The so called 'Celtic' variant of Indo European, divides into two distinct subgroups: P-Celtic (or Brythonic) and Q-Celtic (or Goidelic). Cornish and Welsh are P-Celtic languages, whilst Scottish Gaelic, Irish and Manx are Q-Celtic languages. Breton is most closely related to Cornish, a Southwestern Brittonic language. Welsh and the extinct Cumbric, (both Western Brittonic languages), are more distantly related, and the Goidelic languages (Irish, Manx, Scottish Gaelic) have a slight connection due to both of their origins being from Insular Celtic. There are also enormous variations of Welsh within Wales. 250 years ago people from North West and South East Wales would have had difficulty understanding one another. Not that it would have mattered, because they'd never have met anyway.
