"Nie jestem rybą!"

Translation: I am not a fish!

[siebenneun]

Tak Kanye, jesteś :p

[Fabfifties]

Ale jestem kotem!

[miletskiy]

We know this fact from the previous lessons.

[Euhan1]

We are all fish; lobefinned fish to be precise. It's just that we have been (mostly) living on land the last 370 millon years.

[Euhan1]

Look! This has -2 as of today. I'm sure that downvoting this completely factual comment will change how we came to be here...

It's also a simple fact that a cod fish is more closely related to a human than to a shark. Does that then mean that we shouldn't call sharks fish?

[chce_polski]

How is a cod more closely related to a human? Cods and sharks are in the same phylum: fish. They breathe water, have scales, gills, etc.

I still don't understand why the object (fish) in this sentence takes Instrumental. Looking through the discussions has not been helpful. Does the same rule apply to "Nie jestem fotelem." or "Nie jestem lekarzem" ? Please help.

[Jellei]

Yes, the same. in a sentence built as "[noun] is [noun]" or "[pronoun] is [noun]", the noun after any form of the verb "to be" takes the Instrumental case.

There's a story here behind this one and I'm not sure if I want to know it.

[CanadianPolak]

Sometimes I wonder who comes up with these sentances...

[johnfry7]

I think the intention is just to differentiate between “jestem” and “jem”.

[Jellei]

Well, "Nie jem ryby" (I am not eating fish) takes a different case anyway ;)

[Glen624972]

Back when I wrestled, a "fish" was a wrestler who reached back from the opposite side. In Polish, does fish carry any other meaning besides the literal one?
