Preposition - PE - a close look at this prep The preposition pe can sometimes mean something as a direct translation in english or NOT. Here's how it was explained to me....

pe = on
pe = for
pe = no direct translation
pe = who

pe=on
Let's look at the first instance where pe = on

pe = for
Here pe means for but this is not the usual translation of for. Normally for is written as pentru.

Caut pe vecinii dumneavostra. = I'm looking for my neighbor.
Caut pe vecinii Maria. = I'm looking for my neighbor Maria.
Cauți pe Mircea. = You look for Mircea.

pe=no english equivlent - in english this would be omitted.

Întreb pe avocatul Ionescu. = I ask the lawyer Ionescu.

Ai luat dicționarele? Pe al meu da (l-am luat,) pe al vostru nu (l-am luat.) = Did you take the dictionaries? I took mine, I didn't take yours.*

*In this last example you don't have to say l-am luat, instead it is implied, although i noted where it would be)

pe=who? pe cine? used only with people in the accusative.

Astepti pe cine? = Who are you waiting for?
Astept pe Mihai. = I wait on Mihai.  ¶ 4:06 p.m.
