Russian Grammar 110 – Prepositional Case

Prepositional Case

The Prepositional case is so called because it is always used after prepositions and answers the questions: about who?, About what?, Where? 
The four prepositions that call this case are о/об/обо (about), при (on) в (in), and на (on). 

Usage of prepositional case:

to indicate the location of something or someone we use prepositions -в (in) or -на (on).

To indicate a person or an object being talked or thought about and used after prepositions -о (about).

To indicate time, it is used with name of the months.
