Prepositions governing the prepositional or locative

HA

(a) on, in or at to define location, the place where sth is situated; cf. use of
accusative when movement is involved:

Книгa лeжит нa столe. The book is on the table.

(b) on, in or at before many common nouns, where English-speakers might expect в to be used; many of these nouns denote some sort of occasion, or refer to both the place and the event or activity associated with it:

The prepositional case, as its name suggests, may only be used with certain prepositions (в, нa, о, по, при). It is also sometimes called the locative case, since when used with the prepositions в and нa it may
define location.
