According to the Ethnologue, Puroik is spoken in 53 villages along the Par River in Arunachal Pradesh.
The Puroik language is traditionally assumed to be a Sino-Tibetan language of the Kho-Bwa group. However, the conventional classification of Kho-Bwa languages as Sino-Tibetan is being questioned, quite independently of the additional issue whether Puroik belongs to Kho-Bwa in the first place. In the context of Sino-Tibetan, Puroik is highly divergent, and it is not entirely certain it should be classified as such at all. There is a possibility that it is an Austroasiatic language that changed because of Sino-Tibetan cultural influence. Blench (2011) considers Puroik a language isolate. There is some mutual intelligibility with Bugun, and Burling (2003) grouped it with Bugun and Sherdukpen, and possibly with Lish and Sartang. Besides their own language, the Puroik also use Nishi, Hindi or Assamese. Literacy is very low, at about 2%. Those who are literate use either the Bengali script, Devanagari or the Latin alphabet to write Puroik.
Number is not considered a grammatical feature in Sulung. Plurality is expressed, when required to be stated clearly by the huangda meaning all, many, etc.
There is no grammatical gender in Sulung. However the two sexes are distinguished when necessary. To indicate other relatives and persons the suffix -aphu is added for the male and -amua for the female. Demonstrative, and Interrogative.
Seven cases may be distinguished: Subject (Nominative), Object (Accusative), Instrumental, Dative (Purposive), Ablative, Possessive (Genitive), and Locative.
The Personal Pronoun distinguished three persons (the first person, second person, and third person) and two numbers (singular and plural). The same form is used for both genders.
There are four types of adjectives: adjective of quality, adjective of quantity, demonstrative adjective, interrogative adjective.
Sulung verbs do not indicate number and person. The same for serves all the three persons and both the numbers.
The three principal tenses (present, past, and future), including the indefinite and the continuous are indicated by means of particles used as suffixes.
There are four moods: Imperative, potential, conditional, and subjunctive. Imperative uses the suffix -bo, -da, and -ge for commands. Potential uses the suffix -pa to express the ability to perform. Conditional uses -re/-hangra to express obligation.
Adverbs may be distinguished into four classes: Time, place, manner, and interrogative.
A list of consonants, vowels, and vocabulary can be found on the Endangered Languages page under the *Resources* tab. It includes over 100 Puroik words and phrases. This resource also includes grammar rules and the explanation of gender/number/degree use.
