In linguistic typology, a subject+object+verb (SOV) language is one in which the subject, object, and verb of a sentence always or usually appear in that order. If English were SOV, "Sam oranges ate" would be an ordinary sentence, as opposed to the actual Standard English "Sam ate oranges". (A Grammar of Sunuwar) 
Sunuwar people called "Khangsa" sign language with voice and direct action, for foreign people who don't understand a sunuwar language.
Though Sunuwar is most commonly written with the Devanagari script, a native writing system, Jenticha, has seen limited use since the 1940s.
An endangered language is a language that it is at risk of falling out of use, generally because it has few surviving speakers. If it loses all of its native speakers, it becomes an extinct language. UNESCO defines four levels of language endangerment between "safe" (not endangered) and "extinct":
A prefix is an affix which is placed before the stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix un- is added to the word happy, it creates the word unhappy. Particularly in the study of languages, a prefix is also called a preformative, because it alters the form of the words to which it is affixed.
Prefixes, like other affixes, can be either inflectional, creating a new form of the word with the same basic meaning and same lexical category (but playing a different role in the sentence), or derivational, creating a new word with a new semantic meaning and sometimes also a different lexical category. Prefixes, like all other affixes, are usually bound morphemes.In English, there are no inflectional prefixes; English uses suffixes instead for that purpose.
The word prefix is itself made up of the stem fix (meaning "attach", in this case), and the prefix pre- (meaning "before"), both of which are derived from Latin roots.
