Moje kanapki są duże!

This sentence doesn't make any sense in English

[Jellei]

Or in Polish, or in any language. But it teaches the grammar.

[PatriceLeB9]

Lol! So czyje is for plural?

[Jellei]

It's for 'not masculine-personal plural', so for most plural nouns (apart from those that describe groups of people with at least one man).

For masculine personal, it's "czyi", e.g. "Czyi to synowie?" = "Whose sons are they?".

[Ash473779]

Yes it does, for example, at a picnic, "I don't know who these big sandwiches belong to... Whose sandwiches are big?"

[Euhan1]

Maybe in a commercial. Singing: "Whose sandwiches are big? Homer's Homemade Hoagies'!"

Admittedly it would hard to score but that's a result of bad metre rather than bad grammar.

[Frecklebuster]

Is it the same for 'Whose are the big sandwiches?'

[Jellei]

No. In your question, the subject is "the big sandwiches", and in the original question, the subject is "whose sandwiches".

So I'd translate your question as "Czyje są duże kanapki?", but it'd make a lot more sense to treat "the" as "these" and ask "Czyje są te duże kanapki?"

Isn't it who's????

[martinkl]

"Who's" means "Who is" or "Who has". "Whose" is a word on its own with different meaning

[foo__bar]

whoops :D

[dradski]

Czyi and czyje

[Jellei]

"czyi" - masculine personal plural.

"czyje" - not masculine-personal plural. And neuter singular.

[chce_polski]

Subway's aren't...

[Rulecka]

Czy 'Czyje sa tej duże kanapki?' jest ok??

[Jellei]

If you meant "te" and "tej" is just a typo, then it's ok. Well, after you change "sa" into "są" of course :)

But it means "Whose are these big sandwiches", so it's not exactly the same thing. Even though it actually makes more sense as a sentence.

[Rulecka]

Yes that was a typo, sorry! Thank you!

[Walkinthedog]

I used large on purpose to see if it would be accepted, I feel it should be. ?

[Jellei]

Yes, it's among the accepted answers.
