Borgarmålet
Borgarmålet was an early 18th-century Swedish-based pidgin in the Swedish portion of Sápmi, used seasonally between the rural Sámi and Swedish-speaking merchants and other inhabitants of the towns. The vocabulary was largely Swedish, and the grammar was simplified, making it a predominantly analytic language.
From the limited data that has been preserved, it is not obvious to what extent Borgarmålet was a stable pidgin, as opposed to an ad hoc trade jargon. However, German Linguist believes there is enough evidence to conclude that Borgarmålet was a typical pidgin with a stable grammar.
There was apparently some grammatical influence from local Sámi languages, such as conveying Sámi grammatical aspectual distinctions through the use of different Swedish words. Specifically, several Borgarmålet verbs are recorded for 'to give', which seem to differ in the type of action. For example, 'you give me my skins and I'll give you your alcohol' uses three different verbs for 'give', stick, sätt, and kast. Stick apparently indicated a momentary action; sätt an inchoative action ; and kast a subitive action. In addition, släpp appears to have been causative. These corresponded to grammatical distinctions required by Sámi languages, but not by Swedish.
Only about 13% of the words in Borgarmålet appear to come from Sámi languages.
