Questions & Answers about Við þekkjum nokkra þátttakendur.
Why do we use nokkra here instead of nokkrir?
Nokkra is the masculine accusative plural form of nokkur (several). It must match the noun it describes, þátttakendur, which is masculine, plural, and the direct object (accusative case) of the sentence.
What is the singular form of þátttakendur?
Does þátttakendur change its ending in the accusative case?
Not in the plural! For these -andi nouns, the plural form -endur is exactly the same whether it is the subject (nominative) or the direct object (accusative). Luckily, the quantifier nokkra clearly shows us we are in the accusative case.
I always mix up the verbs for 'to know'. Why use þekkjum and not vitum?
You use þekkja (we know = við þekkjum) when you are familiar with a person, place, or thing. You use vita only when you know a fact or a piece of information. Since you know participants (people), þekkja is the right choice here.
