Rhade (called Êđê by its speakers and also known as Rade, Raday, Rđê, etc.) with its various subgroups (Mdhur, Adham, Blo, Kodrao, Bih, Krung, and Rđê Kpă) was reported by the Summer Institute of Linguistics in 1972 to be spoken by 80,000 to 100,000 persons throughout Darlac and part of Khanh Hoa provinces, centered around Banmethuot.
In this dictionary the alphabetical arrangement used by Pere DaviasBaudrit has been followed with some modifications. The orthography used, including ƀ and đ, is the standard Rhade orthography which has been in use for many years and is familiar to every literate Rhade.
