One of the Miao teachers, Yang Yung-xin, concluded his second collection of old Miao songs with a key to the meaning of some of the seventy archaic words and phrases which occur in the songs but not in current speech. He headed this list, "Old Miao Words", a term which Wang Ming-ji also employed from time to time. These expressions are included in the Glossary but distinguished by the letters OM, meaning Old Miao. In the course of transcribing and translating the songs Keith Parsons has identified many more similar examples, which have been recorded and are also marked OM.
