"We need a person with knowledge of Finnish."

Translation: Vi behöver en person med kunskaper i finska.

[Misieuroo]

So, Swedish uses the plural with the word "knowledge", just like "Kenntnisse" in German and "connaissances" in French. Interesting…

In English knowledge is an uncountable noun - there is no such word as knowledges

I found it interesting that "människa" was not accepted in this sentence. I searched around on the web to gain a better understanding of why person was more natural in this sentence. Here is what I found.

Människa = Human (Neil Armstrong var den första människan som landade på månen)

Person = Person (I min bil får det plats 5 personer)

Folk = A group of people. (Det är mycket folk på stan idag)

Some of the explanations were in Swedish, but I copied the one with English in it.

Can someone explain when to use "kunskap" vs "kunskaper"?
This exercise accepted both options and I'm not sure why.

[AnitaVandi2]

Why has it to be "kunskaper" in plural ?
