Reconstruction

The Welsh forms derive from this form impeccably. The Cornish and Breton forms are a little off though, not just because of dissimilation, but because the vowel development doesn't make much sense to me at the moment. Anglom (talk) 00:56, 12 October 2016 (UTC)

Why does Welsh have mh instead of mp though? Is that really the regular development? I'm aware that Proto-Celtic didn't even have a p. —CodeCat 19:43, 12 October 2016 (UTC)

Welsh had a sound development where internal /mp/, /nt/ and /ŋk/ became /mpʰ/, /ntʰ/ and /ŋkʰ/ I think, before becoming /m̥/, /n̥/ and /ŋ̊/. This is usually represented as ⟨mh⟩, ⟨nh⟩ and ⟨ngh⟩ but not wholly consistently. It apparently didn't apply when word final. This was also integrated into the Welsh nasal mutation, even though it's technically a separate event from the original development of Brythonic nasal mutation.
