Northern Selkup is a Samoyedic language spoken in Yamalo-Nenets Autonomous Okrug and Krasnoyarsk Krai in Russia, by about 600 people. Despite institutional support and grassroots activism, its future "appears gloomy". Some villages have parents transmitting it to their children, but not most.
It is considered to be a dialect of a greater Selkup language by most Russian sources, but an individual language by others. According to lexicostatistics, it can be considered to be an individual language. The Endangered Languages Project states that the differences between the Selkup dialects are "comparable to those between, for example, Ket, Yug, and Pumpokol".
The dialect classification of Northern Selkup is as follows:
The full list of dialects is Upper Taz (around 250 speakers), Middle Taz (about 120 speakers), Baixa and Turukhan (about 40 speakers), and Jeloguj (1 speaker). Both Taz dialects are used in education.
Northern Selkup developed from a 17th-century offshoot of the Tym dialect of Central Selkup.
There are 25 vowel and 16 consonant phonemes in the Taz dialect.
Stress in Selkup varies considerably from dialect to dialect for certain words,
Stress in Selkup is rarely phonemic. Some examples are 'wanted, wanting' 'riverless', and 'make fat' 'lose'.
The Selkups, before the introduction of writing, used a rudimentary way of recording numbers; individual lines for units, crosses for tens, and stars for hundreds, as well as the usage of tamgas.
In 1931, the first Northern Selkup alphabet, in the Latin script, was developed.
A a, B ò, àç, D d, E e, àÃÂ, G g, â ã, I i, J j, K k, L l, M m, N n, à  à Â, O o, àõ, P p, Q q, R r, S s, à  à Â, T t, U u, W w, Y y, Z z, ÷ ÃÂ, ì ÃÂ, àæ
In the end, however, it was slightly modified. This version is the one in which literature was published in.
The Middle Taz dialect was chosen as the base due to a large speaker base and minimal influence from Russian. Letters D d, F f, and H h were only used in loanwords.
The primer uses ê ê and ê¨ ê© instead of àç and à  à Â.
In 1937, the alphabet, like all those of the languages of the Soviet Union, was transliterated into Cyrillic. The first such alphabet took the form of the Russian alphabet, with the extra letters ðü, ýó, þü, þð, ÃÂü, ÃÂü. Books were first published in this alphabet in 1940.
The next alphabet was introduced in 1953, in a primer. The alphabet itself took the form of the Russian alphabet with the extra letters õü, úü, ýü, ÃÂü.
Following this, the only other literature in Northern Selkup until the 1980s was two songs in the collection "áõòõÃÂýÃÂõ ÃÂþÃÂÃÂÃÂÿø", published in 1962.
Writing in the Northern Selkup language was revived in 1986 with the publication of a primer in the Middle Taz dialect, which was followed by other literature. Teaching was also resumed. The first dictionary, published in 1988, used the following alphabet.
àð, àñ, àò, àó, àô, àõ, àÃÂ, àö, à÷, àø, ù, àú, àÃÂ, àû, àü, àý, àÃÂ, àþ, è é, àÿ, àÃÂ, á ÃÂ, â ÃÂ, ã ÃÂ, ð ñ, ä ÃÂ, ÃÂ¥ à, æ ÃÂ, ç ÃÂ, è ÃÂ, é ÃÂ, ÃÂ, ë ÃÂ, ÃÂ, àÃÂ, î ÃÂ, ï ÃÂ
The letters æ ç and ààwere introduced later.
Since the 2000s, with the introduction of the letters ÃÂ ÃÂ and ÃÂ ÃÂ, the alphabet has taken the following form.
Vowel length is indicated by a macron. Letters àñ, àó, àô, àö, à÷, ä ÃÂ, ÃÂ¥ à, æ ÃÂ, é ÃÂ, ê àare only found in loanwords from Russian.
