Could I have used ludzi (is the Genitive Plural caled for?)?

[luless]

You could say : 'jedenastu ludzi' but in this contex I wouldn't sound good.

[tadjanow]

better yet 'jedenaścioro ludzi'

[Namelessghost101]

When do you use osób vs ludzi?

[Jellei]

In plural they seem more or less interchangeable, although technically "osób" means "persons".

[Namelessghost101]

Ahh okay. I tried to use ludzi but it won't accept it. So just curious. Thx for the reply

[Arnoldpitt]

a tiny hospital!

[anothernobody]

Why not jednaście for ludzi?

[mihxal]

"Osoba" is a feminine noun so in plural it is a non-masculine-personal noun. "Człowiek" (plural: "ludzie") is a masculine noun.

[immery]

if you wanted to be inclusive and appreciate that there are women among people you could say jedenaścioro ludzi, but that is tongue twister.

I don't know why but we very often count "osoby" and rarely "ludzi"
