The verse above is very interesting as the numbers nearly all sound like paraphrased Welsh1== Un (pronounced een)
2 = Dau (prodounced Die)
3 = tri (tree)
4 = Pedwar (pethera in the verse)
5 = pump (pronounced pimp)
10 = Deg (dick in the verse)
After ten we have
11=Un ar ddeg (which means literally one and ten) and so on. the word "petheradick" could be pedwar a ddeg (14)The word "Bunkin" could be pumtheg (15)
