Thus, for example, "I am" could be "soy" (=saw-ee) or "estoy" (=es-toy-ee). Soy is used for things that are permanent in nature, whereas Estoy is for those things that are in transition or if it is about location. (the infinitive forms are "ser" and "estar")
Example: I am Amitabh = Soy Amitabh I am ready = Estoy listo
I am from India = Soy de la India I am working = Estoy trabajando
Just wondering why the ancient Spanish people decided to use the 'temporary be - estar' for marriage?!?!?!
