Would you say it's an exception then when in counting how much of something you have, usually the object is in genitive, but when the number ends in 2/3/4 and is not 12/13/14, the object takes the same case as the numeral?
Widzę cztery koty.
Widzę sześć kotów.
Also... Do you have any resources for polish declensions? I'm having a real tough time. Sometimes I think genitive plural will chop off the suffix, sometimes it adds -ów. Help!
Generally you can take a look here: https://www.duolingo.com/comment/16296174 and look through the topics about cases and the resources.
Okay, generally yes: most of them use Genitive, those that you mentioned do not. But the object generally just takes the same case as the numeral, not only in those non-Genitive ones. I mean, if we consider "three cats" as one noun phrase, its Nominative is "trzy koty". And the Nominative of "seven cats" is "siedem kotów". Accusative looks the same as Nominative. But in the other cases, the word 'cats' changes, regardless whether the number is 3 or 7. It changes just as the numeral changes.
Trzy koty (Nom.) Szukam trzech kotów (Gen.) Przyglądam się trzem kotom (Dat.) Widzę trzy koty (Acc.) Rozmawiam z trzema kotami (Instr.) Czytam o trzech kotach (Loc.)
Siedem kotów (Nom.) Szukam siedmiu kotów (Gen.) Przyglądam się siedmiu kotom (Dat.) Widzę siedem kotów (Acc.) Rozmawiam z siedmioma kotami (Instr.) Czytam o siedmiu kotach (Loc.)
Thank you. Teraz rozumiem. In every case but nominative and accusative, cats will be the same case as its numeral. And in nominative or accusative (for most numbers), cats will be genitive. For other numbers, cats will be either nominative or accusative plural respectively.
I'll check out those links.
If it makes sense to treat it as a numeral (0,5 apple), then sure, "pół" seems easier.
It wouldn't make sense in some other sentences, like "Połowa ludzi w biurze jest smutna" (Half of the people in the office are sad), I guess you won't substitute that with "0,5 people" ;)
