Sorry, Porfyhr, but I don't understand what you wrote above. If you linguists try to use the Swedish word whenever possible, why would you prefer the English word here?
We don´t have any other words that are more suitable.
"Partner-s" is a swedish word with its origine in english. We do not, as I wrote, invent new words like the islandics do. We accept foreing words and incorporate them into our language.
Swedish is a small language and therefore are mainly linguists involved in the preservation of the language.
I hope you´ll understand this time.
