"Kiedy są twoje urodziny?"

Translation: When is your birthday?

[FakeShark]

How come this is plural but translates to a singular? Is it because the literal translate of urodziny is something other than birthday?

[AnastasiaStyIes]

It's reasonable, semantically. After all, we have a birthday every year, so it'd be reasonable to ask the equivalent of "When are your birthdays?".

[immery]

while you are right keep in mind that the birthday you celebrate this year is still "urodziny" (It's like Christmas)

[gabe81]

Urodziny is one of the Polish words that are always plural. Just like 'drzwi' (a door/doors) or 'spodnie' (trousers)

[conor.raff]

I didn't know about "drzwi". That makes no sense at all lol

[idanlipin]

Like the rest of the Polish language

Two sides to a door????

[Inge452707]

every door is an entrance and an exit

[alik1989]

Actually, many doors used to have two halves in the past, so that's where the plural probably comes from.

Words which are always in plural are called "Plurale tanum" - more Polish examples (but not only) can be found here https://pl.m.wikipedia.org/wiki/Plurale_tantum. Explanation in English language: https://en.m.wikipedia.org/wiki/Plurale_tantum

How would you ask 'when are their birthdays?'

[Jellei]

"Kiedy są ich urodziny?", "Kiedy mają urodziny?" - as "urodziny" are pluralia tantum.

[Christian7652]

Urodziny here is nominative ,not accusative as indicated.though both forms are identical in this case

[sharinglanguage]

I was about to ask about it. Indeed, the tooltip says it is accusative.

[Jellei]

The tooltip isn't for a specific sentence but all sentences containing the given form, and we were actually asked to get rid of grammatical explanations as they mess up with the tiles exercises - that's why they are relatively rare now. But yes, it's Nominative here.

Moj taty jest 11.IX... :-(

[Jellei]

Mojej cioci też.

P.S. "mojego taty" (Genitive, "my dad's").

[Niall848290]

"When is it your birthday?" was rejected - can someone clear up why thats wrong for the people that come here searching? :)

[alik1989]

Ok, let's add it.
