"Kaczka to zwierzę."

Translation: A duck is an animal.

[linguafiqari]

Could someone explain this sentence? I would have translated it as "Kaczka jest zwierzęciem"

[Viersch]

Both options are correct. More information here: https://www.duolingo.com/comment/12264072

Dziękuję znowu! :)

[missmixie]

why is "is" in this sentence TO and not JEST? Thank you so much!

[idanlipin]

Both ways are correct. Keep in mind after jest, the following noun (or the adjective that comes with it) will be in the instrumental case.

"duck is an animal"
Why would I need any article. I thought it was a correct sentence...

[infinitebuffalo]

in English, we need an article for many more things than most Central and Eastern European languages, though less than some Romance languages....

In this case, both 'a duck...' and 'The duck...' could be correct, but without any article, 'duck' isn't an animal, it's food.

I said "Duck is an animal". I tend to get in trouble even in English for writing passively.

It is so easier to use to than je, not need to use a hard instrumental ending :D

[Jellei]

"je" means "he/she/it eats", you meant "jest" ;)
