unless - if not

Question

Could you tell me if unless is the same of if not over all in the Conditionals use?

would you answer me in English and Spanish to understanding very well?

thanks a lot

Answer 1

Pueden tener el mismo sentido pero cada quien con su propia estructura de frase.

If not for you, my sky would fall (Si no fuera por ti)

Rain would gather, too

Without your love Id be nowhere at all

Id be lost, if not for you (Si no fuera por ti)

(Bob Dylan)

Unless you were here, my sky would fall (Si no estuvieras aquí)

Id be lost, unless you were here (Si no estuvieras aquí)
