Here, you can find the treasure of Nassian - söleesenikü (dictionary) and certeni Nasiko (sample texts).
The historical grammar of Nassian is described in the tikekä aarika Nasiko (historical grammar of Nassian).
Nassian or nasëku
enessükü
is, along with Skuodian, Sievrøsku (Sevorian), Slavëni (Slavieni),
Slavisk, Lydnevi, Jåzaht
Severøn (Seversk), Mrezian and Vozgian,
the representative of the North Slavonic language group. All languages differ
quite a lot because of purpose and origin (e.g.
Sevorian is agglutinating,
whereas Slavieni, Seversk and Nassian are inflective).
Nassian also differs from East Slavonic languages
quite a lot, because ancestors of the present speakers of Nassian
diverged from the common Slavonic language before the west and east language
groups
were formed, approximatelly in the 4th cc E.C. However, there
are some similarities between Nassian and the West and South Slavonic languages.
Moreover,
modern Nassian is
almost not influenced in lexica by the Scandinavian substrate (although mostly
because of language purists, so called language brushers - enezükäpuursäki).
(brief description of Nassian and its dialects)

N. evolved through several states; from early Proto-Slavonic (rana pärsöleenikä, EPSL) common to all Slavs to early ancient Nassian (rana pärnäsikä, EAN), which was constituted from dialects of Slovianians and Ilmenians. These dialects were touched by Gothic influence, but were more influenced by Baltic languages (e.g. absent classical metathesis of liquids). EAN represents the first influence of an early separation of future Nassians and influence of Finno-Ugric languages. Later, in old Nassian (särrä nasika, ON), these changes started to be propagated more vissibly, because of a spread of literacy. Classical Nassian (nasika, CN) represents language under influence of Swedish culture, whereas modern language (malta nasika, MN) is a opus magnus of 19th cc linguists and purists.
N., as any other language spread accross geographically articulate territory, has developed several dialects: Settikortian (Sk, sëttikortëki reki; green), dialects of town Settikortt, the administration center of the country. S. dialects were heavily contaminated by lexica comming from Swedish and Riksmål, which were mercilessly, and often insensitivelly, "brushed off" during Nassian National Revival in second half of 19th cc E.C. Karelian (Ka, käräleki reki; gray) dialects are far from center, more rural and have been influenced more by Finno-Ugric languages, such as extinct Karelian. On the other front, N. was influenced by Russian language. That has established south-east dialects: Ladogo-onegian (No, neppö-eniseki reki; orange). They are close to Russian in many ways, e.g. re-introduction of palatals and of course in lexica.
Other languages spoken in Nassland are Finnic (Mo, mocinëku enessükü; blue) on west borders with Scandianvian Union, Low German (Dn, tolu nemekü e.) as a bussiness language in Baltic League (Pelömörekä Sepíkätä) and Rigsmål (ressekü enessükü) as a bussiness language in Scandinavian Monetary Union.
