Materials for teaching the Lakhóta language developed by the University of Colorado Lakhóta Project are written in a special new orthography. This orthography, and rules for its use, differ enough from other systems which have been used for writing Dakota dialects to warrant a description of the principles and thinking upon which the system is based. The presentation has been made as nontechnical as possible to make it easily understood by non-linguists.
