Conlang/Make an Alphabet
Step One is to create an alphabet, and come up with the sounds.
Example: B, D, F, G, H, K, L, M, N, P, R, S, SH, T, V, W, Y, and Z as in English. C as CH, DH as hard TH (this), J as French, TH as soft TH (thistle).
For vowels our language will have long and short vowels, short distinguished by two dots. Long vowels are as Spanish or Latin. Short for A, E, I, O, U are pat, bet, pig, paw, but. Vowel pairs are ai- my, au how, oi- boy.
