"मेरे दादा छत पर हैं।"

Translation: My grandfather is on the terrace.

No one is talking about the poor grandpa

क्योंकि हम हिंदी पढ़ रहे हैं, fictional characters के बारे में बात नहीं कर रहे हैं।

I wrote "my grandpa's on the roof" unsure why it got marked as wrong?

[suggesta]

Report it

[CathyIsAwesome]

I said patio instead of terrace and d it was marked wrong. Aren't they the same thing?

[RanzoG]

lol, no.
छत is ROOF, and also terrace due to the structure of lots of Indian houses, yes. But if you remember it as roof, you won't confuse it with patio :)

[sunitakuma9]

Before (on) is not use of (are)???

[OJFord]

Do you mean after on, पर, why is it हैं with the ं?

Because it's respectful to दादा जी to use the plural 'are' instead of singular 'is'.

[anika.kokate]

I write there grandfather is in the terrace and it said it is wrong

[OJFord]

Firstly, it's 'my' rather than 'their'; and it does need to be 'on' the terrace, not 'in'. 'In' is like actually ‍inside something, अंदर, you can be 'in the house' because the roof covers you and the walls surround you, but the terrace is merely beneath you, so it's 'on the terrace'.
