todo, etc.

Question

When, if ever, should todo (a,os,as) be followed by the preposition "de"?

Accepted Answer

Hola Gerald
I can't think of any context where we'd use todo followed by "de". We use todo as a pronoun:

Lo has hecho todo. 
You've done it all.

As an adjective:

Todos los días
Everyday
Todo el pollo
The whole chicken

But we don't use the preposition "de" (I imagine you're thinking about the English "all of something", as in for example "all of Scotland", "all of it", "all of the students"?). We'd say:
Toda Escocia
Todo eso/ello
Todos los estudiantes
...
