Editing Tysfjord Municipality (section)

===Name===
The municipality (originally the [[prestegjeld|parish]]) is named after the local [[Tysfjorden]] since it was a central geographical feature in the area. There are several ideas on the derivation of the name. Historically, the name was spelled in Norwegian as ''Tyttisfjiorden''. One thought is that the first element was the old name for the fjord {{lang|non|Þýtir}} which may have come from the verb {{wikt-lang|non|þjóta}} which means "blowing" (as in wind) or "rushing". The last element is {{wikt-lang|non|fjord}} which means "[[fjord]]". Another thought is that the name ''Tysfjord'' is a Norwegianized form of the [[Lule Sami language]] name for the fjord, {{lang|smj|Divtasvuodna}}. The meaning of the first element {{lang|smj|divtas}} is unknown and the last element is {{wikt-lang|smj|vuodna}} which means "[[fjord]]". Another popular belief is that the Norwegian name is derived from the [[genitive case]] of the name of the [[Norse mythology|Old Norse]] god [[Týr]], but is the least plausible since the name ''Týr'' does not seem fit either with the Sami form or the oldest Norwegian spellings of the name.<ref>{{Cite book |last=Rygh |first=Oluf |author-link=Oluf Rygh |url=https://books.google.com/books?id=K21BAAAAIAAJ |title=Norske gaardnavne: Nordlands amt |publisher=W.

Historically, the name of the municipality was spelled ''Tysfjorden''. On 6 January 1908, a [[royal decree|royal resolution]] changed the spelling of the name of the municipality to ''Tysfjord''.<ref>{{Cite journal |year=1908 |title=Norsk Lovtidende. 2den Afdeling. 1908.

It is called {{lang|smj|Divtasvuodna}} when it is spelled alone, but it is {{lang|smj|Divtasvuona suohkan}} when using the Sami language equivalent to "Tysfjord Municipality".<ref name="sami name" />
