Ir + ser/Futuro imperfecto

Question

Hello I'd like to ask you a question.The thing is : Are 'ir + ser' construction and futuro imperfecto tense interchangeable? I've been taught that 'ir + ser' is similar to 'going to', but somebody has told me that in the informal speech we only use 'ir + ser'. So can we say f.ex 'voy a estar en casa a 9.00'?

Thanks

Answer 1

Your "Voy a estar en casa a las nueve" was almost right. Even if you don't spell the number you need the expression "a las" to mean "at" with reference to time.

And to my knowledge, and I"ve spoken Spanish all my life and have never heard of a "future imperfecto" The future tense refers to events in the future. The imperfecto refers to incomplete action in the past.

Oh, what I've done! Of course I mean 'ir + infinitivo', not 'ir +ser'
