Questions & Answers about لدينا موعد في المستشفى بعد ساعة.
In this sentence, لدينا means we have.
Arabic usually does not use a separate everyday verb equivalent to English have in sentences like this. Instead, it often uses a preposition-like word plus a pronoun:
- لدى = roughly with / at the possession of
- نا = us / we
So لدينا موعد literally comes out something like At/with us is an appointment, which is the normal Arabic way to say We have an appointment.
This is very common in Arabic:
- لديّ سؤال = I have a question
- لديه سيارة = He has a car
- لدينا موعد = We have an appointment
Because the we is already built into لدينا.
The ending -نا means us / our / we in this kind of structure. So Arabic does not need a separate subject pronoun here.
Compare:
- لديّ = I have
- لديك = you have
- لدينا = we have
So the sentence already contains the idea of we inside the word لدينا.
