More verb terminology

Since you guys answered that one so fast, how about a more difficult one? :)

My verbs change meaning depending on what the case of the noun is. For
example:

ga ri ogat
it-NOM be-in room-LOC
"it is in the room"

gar ri ogat
it-AGT be-in room-LOC
"it puts (something) into the room"

gan ri ogat
it-PAT be-in room-LOC
"it goes into the room" or "it is caused to enter the room"

Now, my participles and infinitives need to distinguish between these
meanings. They use prefixes to do that. For example:

t'ri
NOM-be-in
"to be in"

k'ri
AGT-be-in
"to place in"

r'ri
PAT-be-in
"to go in"

What should I call these prefixes? Is there a name for "the quality of a
verb to change its meaning depending on the case of associated nouns"?
