"Kupuję dwa pająki."

Translation: I am buying two spiders.

[Euhan1]

Like for a snack?

[obado]

Mam dwa pająki w domu, że możesz wziąć

[WrzodX]

Correctly: "Mam w domu dwa pająki, które możesz wziąć".

I changed the order because if possible, the desired noun should stand near "które". Otherwise someone might think they can take your house (although it'd be correctly "który").

[centaurii]

It seems the Poles like pet tarantulas too.

[Henryk7]

yes, we like all animals, mythological creature - half human, half horse too :-)

[FaizalZahid]

Centaur, you mean?

[Euhan1]

More like a horse but human below the waist.

[Henryk7]

No, I was thinking about this beautiful "centaurii" with the cat above us :-)

[FaizalZahid]

Sorry but I don't get it

[Jellei]

The app shows a different username than the website, and one of the users above is nicknamed "centaurii" on the website.

[BenConway6]

I wkładam je do but mojej żony.

[Jellei]

"butów" :) Or "buta" if you meant one by any chance.

Ufff, and I thought that your Polish is perfect, but at last, some mistake :D

[BenConway6]

Ah yes, I was thinking the singular was buta. So I should say 'Wkładam je do butów mojej żony'. ;-)

[Jellei]

"buta" is a word (not a common one though), it seems to translate to "haughtiness" or simply "arrogance".

[benulo]

Why would you buy that

[Dimker]

So that they would entertain each other.

[Kulink]

In the slow version of the audio, 'dwa' sounds like 'nefaa'

[MarjanvanK]

why you can say : I buy ?

[Jellei]

It's technically a correct answer. Yeah, you probably need more context for it, but it's not wrong.
