Possible influence on Sámi languages

The earliest Sámi joik texts written down refer to the world as Skadesi-suolu in Northern Sámi and Skađsuâl in Skolt Sámi, meaning " Skaði 's island". Svennung considers the Sámi name to have been introduced as a loanword from the North Germanic languages; " Skaði " is the jötunn stepmother of Freyr and Freyja in Norse mythology. It has been suggested that Skaði to some extent is modelled on a Sámi woman. The name for Skaði's father Þjazi is known in Sámi as Čáhci, "the waterman"; and her son with Odin, Sæmingr, can be interpreted as a descendant of Saam, the Sámi population. Older joik texts give evidence of the old Sámi belief about living on an island and state that the wolf is known as suolu gievra, meaning "the strong one on the island". The Sámi place name Sulliidčielbma means "the island's threshold" and Suoločielgi means "the island's back".

In recent substrate studies, Sámi linguists have examined the initial cluster sk - in words used in the Sámi languages and concluded that sk - is a phonotactic structure of alien origin.
