Tried pronouncing the Welsh alphabet and vowels with hilarious results but it's interesting because they don't have 26 alphabets. They have 28. Also, letters such as J, K, Q, V, X, or Z do not exist in the alphabet, although there are "borrowings" from the English alphabet as you might discover later.

As such, these are the letters in Welsh:

A, B ,C ,Ch, D, Dd, E, F, Ff, G, Ng, H, I, L, Ll, M, N, O, P, Ph, R, Rh, S, T, Th, U, W, Y

And to leave you, here's something written in the Welsh alphabet. *wink*

Gwd lwc. Ai hop ddat yw can ryd ddys and ddat yt meiks sens tw yw. Iff yw can ryd ddys, dden yw ar dwing ffaen and wil haf no problems at ol yn lyrnyng awr ffaen Welsh alffabet.
