"Twoje urodziny nie są w październiku."

Translation: Your birthday is not in October.

[tylerthehun]

Why do you use plural są instead of jest here?

[immery]

because urodziny are always plural,

[TheOdThing]

But... it is...

[Stefan411810]

Although "your birthdays are not in October" is not a normal usage in English, it is not incorrect. I have a birthday every year and they are not in October. Native Polish speakers may understand the Polish sentence to imply singular, but for native English speakers, allowing the literal translation as a correct alternative would help us .

We'd prefer to stick to the normal usage though. We don't want people who are not native English speakers to think that this is a common thing to say in English, after all this course is also taken by people wanting to improve their English. And when a Polish person say "urodziny", we rather don't think "they are every year in October"...

[PremGopalG]

Why is 'your birthdays are not in October' incorrect? How would you say that sentence?

[alik1989]

Twoje is referring to one person, but one person can't have multiple birthdays within one month.

[Pam833405]

One could, but under very extenuating services

[Carlos551800]

Because, even though in Polish is plural, in English to refer to only one birthday is always singular

[Pam833405]

Okay, so since twoje is singular, the speaker is basically saying 'all your birthdays aren't in October , referring to the person's lifespan...rather unwieldy

[alik1989]

No, the speaker says exactly what is displayed in the main translation.
