However, I think it shouldn't be accepted because "birthday" only refers to people's birthday in English. "Anniversary" is for places, events, etc. And if a thing possess something it's not "her" possession; it's its possession.
And even in Portuguese "Amanhã é aniversário dela" will refer to a person in 99% of the cases. If I would inform someone that my city's anniversary is tommorow I would probably "Amanhã é aniversário da cidade" or "Amanhã é aniversário de [city's name]". In fact, I can only think in a situation that "Amanhã é aniversário dela" would refer to something else: "Essa cidade é tão linda. E amanhã é aniversário dela". However, in English it will be "This city is so beautiful. And tommorow is its birthday", not "her".
Hm, I wondered about it a bit, and I was able to think a situation in which "her anniversary" would be fine. One can say "Today is my wedding anniversary. Tommorow is her anniversary" (although probably one would say "Tomorrow is hers" in fact or "Tomorrow is her wedding anniversary").
However, it's an unlikely scenario and an exception, so I still mantain my first opinion.
I had "Tomorrow's her birthday" but it was marked wrong. English native speakers, would you find that acceptable?
That's perfectly good English. The apostrophe only denotes an absence. It is not exclusively possesive.
I was lead to believe that using o in front of aniversário dela was necessary. Can someone explain to me when you might use it or not?
What's wrong with "Tomorrow is her anniversary" -- in English, one would assume her wedding anniversary without further context. Does the interpretation default to birthday in Portuguese?
In a general context, if you say just "aniversário" we refer to birthday. Then, you'd say "é o aniversário de casamento dela"
Is there another word for birthday? I know in Spanish we say "cumpleaños" or "aniversario"
none that i have learned up to now.maybe in another region but i've always heard birhday as aniversário
Your portuguese seems very sharp, congrats. However I should say this is more a slang. My parents wouldn't use this abbreviation. I think they would guess the meaning, but they wouldn't use.
I agree with Paulenrique. I think there is no other word for aniversário in Portuguese.
In spanish we do not use "aniversario" as birthday. aniversario, ria. (Del lat. anniversarĭus 'que se repite cada año'). 1. adj. p. us. anual. 2. m. Día en que se cumplen años de algún suceso. 3. m. Oficio y misa que se celebran en sufragio de un difunto el día en que se cumple el año de su fallecimiento. Real Academia Española © Todos los derechos reservados
Is the pronounciation of dela [djela] or [dela] (I'd rather have it in Portuguese from Portugal please)? I think I'm messing up ;)
D sounds like /dj/ when it is followed by the letter i or DE at the end of a word, because then the E sounds like i (dia, diálogo, verde - all these D sounds like dj) All the rest (da, de, do, du) sounds similar to D in English (dedo, dado). (sidenote: in some regions in Brazil, the letter D sounds exactly the same no matter if it's followed by the letter i - they all sound like D not dj.)
No, the person whose birthday is being celebrated is called "aniversariante". So it should be "Parabéns à aniversariante" (if it's a woman; and "Parabéns ao aniversariante", if the person is a man). Also, you've used the wrong diacritical mark.
The problem is that some hints, although correct, are not relevant to the sentence presented. That's true here. When "É" begins a sentence or phrase, "It is" or "It's" is often the best translation, but with a defined subject then "is/are" is the correct choice. For example, "É uma emergência" (It's an emergency), "Ela é inteligente" (She is clever) and "Você é minha amiga" (You are my friend).
Thanks for your information! (It's already the second time you gave me advice, so take a lingot! Also, I have more than enough anyway. :')) The thing that makes it even more hard is that English is not my first language, so it's difficult for me to not make stupid mistakes like these. Therefore I would like a Portuguese course in my own language very much, but unfortunately still no seems this is going to happen. But still, I find it very frustrating these hints are wrong, and already submitted a lot of reports about this.
