"These are your grandfather and grandmother."

Translation: ये आपके दादा और दादी हैं।

[Lesley721067]

Please explain how are we supposed to know whether they are maternal or paternal grandparents when translating from English?

[vinay92]

It should accept both दादा, दादी (paternal grandparents) and नाना, नानी (maternal grandparents). You can report the sentence if it doesn't.

[OJFord]

It does, just for fun I tried दादा और नानी, which worked too.

Why is ये तेरे दादा-दादी हैं incorrect?

[vinay92]

Just splitting hairs. दादा-दादी is 'grandparents' whereas दादा और दादी is 'grandfather and grandmother'.

[Translingual]

ये आपका दादा और आपकी दादी हैं ?

[Grooooot24]

Why isn't apne used here?

[OJFord]

अपने is a 'reflexive' pronoun, used to refer back to ('reflect') the sentence's grammatical subject; in this case that's ये, so using अपने would be like trying to say 'they're their own grandparents'.

(But it doesn't necessarily have even that sort of maybe-usable for comic effect meaning in Hindi, it might just be gibberish, I'm not sure.)

[DanaSavage]

Idiomatically, how much does it matter if I say दादा और दादी or दादी और दादा? Here the direct translation was 'grandfather and grandmother', but conventionally, what do people say?

[vinay92]

When you separate the words with an और, it's a toss-up between the two but in the hyphenated form to say 'grandparents' (because Hindi does not have a single word for this), दादा-दादी is more common. Similarly, नाना-नानी for maternal grandparents. However, while saying 'parents', the mom comes first - माँ-बाप or माता-पिता.

Why ये आपकी दादा और दादी हौं gets a typo error ?

Why आपके is correct isn't the feminine words gets superiority over plural subjects ??

[vinay92]

For mixed gender groups, you should use the masculine plural form.

दादा और दादी and दादा-दादी one and the same thing (-) consider (and,और) in this way my ans is correct.

[OJFord]

Means the same thing, but दादा-दादी is a bit more like 'grandparents' in English, and Duolingo seems to strictly require those translations - i.e. और form -> 'grandmother and grandfather', and '-' form -> 'grandparents'.
