I'm listening to Language Transfer for Spanish and on one lesson he was saying "Lo esperaba" for "You were waiting (formal)" and then the next lesson he was talking about "Usted quemaba (formal)" for "You were burning".
I know the verbs are different but I was wondering about the structure of Usted vs Lo usage.
To be clear; would "Usted esperaba" and "Lo esperaba" be the same thing? Different? Or even possible? Same for "Lo quemaba (la cena)" and "Usted quemaba (la cena)"?
He didn't use all these words but I'm wondering about Lo (formal you) vs Usted. Is one a direct/indirect object and the other a clarifier?
Could I combine the two to make "Usted lo esperaba?"
