Sami or Saami is a general name for a group of Uralic languages spoken by the Sami people in parts of northern Finland, Norway, Sweden and extreme northwestern Russia, in Northern Europe. Sami is frequently and erroneously believed to be a single language. Several names are used for the Sami languages: Saami, Sámi, Saame, Samic, Saamic, as well as the exonyms Lappish and Lappic. The last two are, along with the term Lapp, considered derogatory by many.

The Sami languages form a branch of the Uralic language family. According to the traditional view, Sami is within the Uralic family most closely related to the Finnic languages (Sammallahti 1998). However, this view has recently been doubted by some scholars, who argue that the traditional view of a common Finno-Sami protolanguage is not as strongly supported as has been earlier assumed, and that the similarities may stem from an areal influence on Sami from Finnic.

In terms of internal relationships, the Sami languages are divided into two groups: western and eastern. The groups may be further divided into various subgroups and ultimately individual languages. (Sammallahti 1998: 6-38.) Parts of the Sami language area form a dialect continuum in which the neighbouring languages may be to a fair degree mutually intelligible, but two more widely separated groups will not understand each other's speech. There are, however, some sharp language boundaries, in particular between Northern Sami, Inari Sami and Skolt Sami, the speakers of which are not able to understand each other without learning or long practice. The evolution of sharp language boundaries seems to suggest a relative isolation of the language speakers from each other and not very intensive contacts between the respective speakers in the past. There is some significance in this, as the geographical barriers between the respective speakers are no different from those in other parts of the Sami area.

The Sami people, also spelled Sámi or Saami, are the indigenous people inhabiting the Arctic area of Sápmi, which today encompasses parts of far northern Sweden, Norway, Finland, the Kola Peninsula of Russia, and the border area between south and middle Sweden and Norway. The Sámi are the only indigenous people of Scandinavia recognized under the international conventions of Indigenous peoples, and hence the northernmost indigenous people of Europe.Sami ancestral lands span an area of approximately 388,350 km² (150,000 sq. mi.), which is approximately the size of Sweden, in the Nordic countries. Their traditional languages are the Sami languages and are classified as a branch of the Uralic language family. The Sami languages are endangered.

Traditionally, the Sami have pursued a variety of livelihoods, including coastal fishing, fur trapping and sheep herding. Their best-known means of livelihood is semi-nomadic reindeer herding, with which about 10% of the Sami are connected and 2,800 actively involved on a full-time basis. For traditional, environmental, cultural and political reasons, reindeer herding is legally reserved only for Sami people in certain regions of the Nordic countries.

Traditional knowledge (TK), indigenous knowledge (IK), traditional environmental knowledge (TEK) and local knowledge generally refer to the long-standing traditions and practices of certain regional, indigenous, or local communities. Traditional knowledge also encompasses the wisdom, knowledge, and teachings of these communities. In many cases, traditional knowledge has been orally passed for generations from person to person. Some forms of traditional knowledge are expressed through stories, legends, folklore, rituals, songs, and even laws. Other forms of traditional knowledge are expressed through different means.

Traditional knowledge has been defined as "a cumulative body of knowledge, know-how, practices and representations maintained and developed by peoples with extended histories of interaction with the natural environment. These sophisticated sets of understandings, interpretations and meanings are part and parcel of a cultural complex that encompasses language, naming and classification systems, resource use practices, ritual, spirituality and worldview."
