This paper describes a system for Choctaw orthography and discusses the principles and rules that can be used to govern the spelling system for the language. The orthography system is based on a study of documents written by comtemporary Chocktaws. The system proposed here seeks to be as accurate a representation of the spoken language as possible while providing a more or less uniform spelling for each morpheme; the vowel and consonant systems are discussed. Where both these conditions cannot be met, the criterion of accurate representation is preferred. The overriding consideration is to achieve a spelling system that is acceptable to a speaker of Choctaw and easy for him to learn, essentially a phoneme system. A sample text with translation is included. For a related document on Choctaw morphology, see FL 002 865. (VM)
