Questions about verbs with a preposition

Questions about verbs with a preposition - colloquial

As with verbs without a preposition, you can ask for the prepositional addition. As with questions about an accusative or dative addition, a distinction is made between "things" and "people":

Example: Verb without a preposition
I see the man. - personWhom do you see?
I see a tree. - ThingWhat do you see?

Example: verb with preposition
I am waiting for the man. - personOn whom are you waiting?
I am waiting for the bus. - ThingOn what are you waiting?

However, the questions with the preposition + apply What (Example: on what?) as colloquial.
