If 'a' is a contrasting 'and' it should accept using 'while' as well here
Can "и" be used here instead of "а" as well?
No.'а' is used here for contrast places
...and и is used for similarity between the two, e.g. ‘Мама здесь и папа тоже.’
This is my German Shepherd Dog's frustration every day...
Dad is over there not accepted?
So typical for the modern family...
Why is 'а' used instead of 'и'? And are they interchangeable? Thanks!
«а» is used to show contrast: «Я танцую, а ты, не»; on the other hand, «и» is used to show similarity: «Ты ешь и пьёшь».
