Geographical distribution of Lun Bawang/Lundayeh speakers
Lun Bawang or Lundayeh is the language spoken by the Lun Bawangs. It belongs to the Malayo-Polynesian family. The first published material written fully in Lun Bawang is a translation of the Bible from 1982, which is called Bala Luk Do. A Lun Bawang–English dictionary was constructed in 1969 by the University of Washington. A dialect of the Lun Bawang language, Kemaloh Lundayeh, was compiled in 2006 into a bilingual dictionary of Lundayeh and English. Lun Bawang is mainly an oral language. There is very little printed written material in this language that was not written by missionaries or linguists. The oral culture of the Lun Bawang people is changing though, with the accessibility of the Internet and Facebook. "Putoh" is an alternate name in East Kalimantan.
There are 6 vowels, 18 consonants and 5 diphthongs in the Lun Bawang language.

Our Father, who art in heaven, hallowed be thy name. Thy kingdom come, Thy will be done on earth as it is in heaven. Give us this day our daily bread, and forgive us our sins, as we forgive those who sin against us. Do not lead us into temptation, but deliver us from evil. Amen. For the kingdom, the power, and the glory, are Yours now and forever. Amen. (Matthew 6:9-13)
