The word "heimsleg" is Nynorsk word. The spoken dialect of Tarjai Vesaas is closes to the Nynorsk written form. But being from the South East my dialect maps closest to the Bokmål written form, which is thus what I read and write.

Hence "hemsleg" is not a word I am that familiar with. In my dialect I would likely say "hjemmekoslig," but it is hard to know whether the breath of the meaning is entirely the same.

Different dialects put different meanings into words. Maybe you are already familiar with this. I don't' know well you now Norwegian. But for anyone curious, Norwegian as a language is split into multiple dialects and written forms. The various dialects will be closer to one written form than another.

Although at times it can be hard to decide which one is closer. Thus people typically choose which written form they prefer, and I know some areas of Norway have transitioned from one written form to another as dialects have shifted.

The written forms I know of are Nynorsk, Bokmål, Riskmål and Samnorsk. Only the two former are official. Riskmål is a posh variant of Norwgeian which was often used by the conservative newspapers. Samnorsk was an attempt at unifying all the written forms into one written Norwegian for all Norwegians.

Nynorsk is a written form constructed based on how Norwegians in the 1800s where broadly speaking. Bokmål is a hybrid between Danish and Norwegian, based of how the educated classes in the towns and cities where speaking in the 1800s. Having been close to the Danish rulers for hundreds of years they had developed a hybrid language.

So yeah, Norwegian is a bit of a mess language wise. There is a rich variety of words found in various dialects which I don't know very well. Areas like Trøndelag, Nord Norge, Vestlandet etc have their own rich language traditions.
