What the hell..? :D

He was told not to!

[YariMsika]

Why is it not ryba??

[maria105105bb]

Because you need to use Accusative Case here. Ryba- is a feminine gender. In Accusative Case the ending is -ę for such nouns.

[YariMsika]

Thanks for the answer, Cases are so confusing! :/

[nyanyan52]

Cases are really simple and easy once you get the hang of them.

[Yeilder1]

Isnt anything easy once you get the hang of them though? lol

[AlexanderM835]

Agreed

[Beata841031]

It is "rybę"

[Phil437025]

I’m having trouble understanding when a noun should be in the accusative or instrumental case. For example Rybą vs Rybę in this sentence.

I don't have the Polish characters in my phone, how to get them?

[Jellei]

May I recommend installing SwiftKey, then you can have up to 5 different languages on one keyboard, with all the diacritics. And then of course you just have to press a 'normal letter' for a longer time to see the diacritics.

[Upl1fted]

And how to type the polish letters with a normal keyboard?

[Jellei]

Well, first you need to change your PC keyboard to Polish, and then it's either left ctrl+left alt+the 'normal' letter; or right alt+the 'normal' letter.

Ż is under Z, Ź is under X.

[Mitchell_NL]

Why is kaczka feminine and not masculine like many words that and end with an "a"?

[Jellei]

Almost all words that end with -a are feminine, those that you refer to are exceptions.

Why are animals bad for the way they are created?

[Jellei]

This duck robbed the fish store a day earlier.

[ognyan]

Why "Niedobra kaczka je ryba. " is not correct?

[Jellei]

"niedobra" isn't exactly the same as "bad", it's more like "not good", although perhaps in this sentence it could be a good translation.

But "ryba" is surely the wrong form. The verb "jeść" (to eat) takes a direct object in Accusative, which would be "rybę".
