Orthography 

From March 18 to March 25 of 2002 in Kasonomu village the current orthography was developed during the Doromu Alphabet Design Workshop. The orthography developed from this workshop were discussed with various areas in the language group and were agreed upon. One problem was how borrowed words with letters not contained in the Doromu orthography would be dealt with. The proposed solution from the native speakers was to spell the loan words as they are spelled in their original language.
