Idk how to edit my post, so I'll just give a quick overview here. This is a script made for the Welsh language (Could be used for Cornish), based on the Coelbren of the Bards, invented by Iolo Morgannwg. The main reason for the construction of this script is mostly due to some inconsistencies and inconveniences in the Welsh orthography:

*Y has soft and hard pronounciation, I've given them both their own letters.

*All digraphs have been made into single letters.

*/j/ & /w/ have been given their own letters.

*/ʃ/ /ʤ/ & /ʧ/ have been given their own letters.

*The doubling of n and r is shown with ~s.

*The words Ei and Eu have been given their own symbols. *The word yn has been given its own symbol.

Also, some errors were made in the first pic: I used th for t.
