Northern or North Sámi ( ; ; ; ; ; disapproved exonym Lappish or Lapp) is the most widely spoken of all Sámi languages. The area where Northern Sámi is spoken covers the northern parts of Norway, Sweden and Finland. The number of Northern Sámi speakers is estimated to be somewhere between 15,000 and 25,000. About 2,000 of these live in Finland and between 5,000 and 6,000 in Sweden, with the remaining portions being in Norway. History Among the first printed Sámi texts is Svenske och Lappeske ABC Book ("Swedish and Lappish ABC book"), written in Swedish and what is likely a form of Northern Sámi. It was published in two editions in 1638 and 1640 and includes 30 pages of prayers and confessions of Protestant faith. It has been described as the first book "with a regular Sámi language form". Northern Sámi was first described by Knud Leem (En lappisk Grammatica efter den Dialect, som bruges af Field-Lapperne udi Porsanger-Fiorden) in 1748 and in dictionaries in 1752 and 1768. One of Leem's fellow grammaticians, who had also assisted him, was Anders Porsanger, himself Sámi and in fact the first Sámi to receive higher education, who studied at the Trondheim Cathedral School and other schools, but who was unable to publish his work on Sámi due to racist attitudes at the time. The majority of his work has disappeared. In 1832, Rasmus Rask published the highly influential Ræsonneret lappisk Sproglære ('Reasoned Sámi Grammar'), Northern Sámi orthography being based on his notation (according to E. N. Setälä). Assimilation The mass mobilization during the Alta controversy as well as a more tolerant political environment caused a change to the Norwegian policy of assimilation during the last decades of the twentieth century. In Norway, Northern Sámi is currently an official language in the county Troms og Finnmark and six municipalities (Kautokeino, Karasjok, Nesseby, Tana, Porsanger and Gáivuotna (Kåfjord)). Sámi born before 1977 have never learned to write Sámi according to the currently used orthography in school, so it is only in recent years that there have been Sámi capable of writing their own language for various administrative positions. In the 1980s, a Northern Sámi Braille alphabet was developed, based on the Scandinavian Braille alphabet but with seven additional letters (á, č, đ, ŋ, š, ŧ, ž) required for writing in Northern Sámi.
