"A bird is eating a mouse."

Translation: Ptak je mysz.

[Khawnduan]

Can someone please tell me does a bird eat a mouse

[Frank528974]

Yes many birds do, not only hawks and eagles, but even our chicken sometimes like mice ;-)

[chce_polski]

Też sowy ich jedzą.

[Jellei]

"je jedzą" :) "ich" is for 'masculine personal plural', so it implies... well, eating people.

[Ash473779]

I thought the noun is supposed to change if it's in accusative unless it's an inanimate masculine noun?

[Jellei]

Well, yes. So I guess this is an exception... it is an unusual noun after all, looking masculine but being feminine.

[RiccardoRo965963]

This is the reason why is not mysza? Because I was expecting it would end up with -a being animated and masculine.. So in reality it is feminine, did I get the concept?

[Jellei]

"mysza" is an existing word, but it is considered colloquial, so we do not teach it nor accept it.

Yes, "mysz" is feminine even if it doesn't end with -a.

I thought it was: ptak jej myszke? Help.

[Vengir]

„Myszka” is a diminutive form of „mysz”. The standard form is „mysz”, which in accusative is also „mysz”.

[fifty-six]

Would it be ok to write in that instance: Ptak je myszkę?

[krwq]

If it's a computer mouse then yes

[Vengir]

Haha, I've just pictured that :D

[Khawnduan]

Me too

[Vengir]

If you wanted to note, that the mouse is smaller than most mice, or that it's a cartoon or a fairytale mouse – sure, you can.

[Khawnduan]

Jej doesn't make sense in Polish it's more like je or jem

[JerryMcCarthy99]

Well, there is a word "jej" in Polish, and it's very common actually, but it has a completely different meaning. "Jem" and "je" are similar, but the former is for the first person, while the latter is for the third.
