Relative pronouns with prepositions (cu care, despre care)

No Dangling Prepositions

In English, it's common to drop the relative pronoun or leave a preposition at the end of a sentence: "The expert I collaborate with." In Romanian, you cannot drop the relative pronoun care (which / whom), and the preposition must always come directly before it.

Collaborating (cu care)

When elaborating on the people you work or interact with, combine the preposition cu (with) and the relative pronoun care.

The expert I collaborate with is very intelligent.
Expertul cu care colaborez este foarte inteligent.
The researcher I went to the conference with is Romanian.
Cercetătorul cu care am mers la conferință este român.

Discussing and Referring (despre care, la care)

Different verbs require different prepositions. We talk about a theme (despre), but we refer to a theory (la).

The theme we are talking about is for today's debate.
Tema despre care vorbim este pentru dezbaterea de azi.
Is the theory you are referring to interesting?
Teoria la care te referi este interesantă?

Relying on Someone (pe care)

To say you "rely on" someone or something, use the reflexive verb a se baza followed by the preposition pe (on). In a relative clause, "the expert I rely on" translates literally to "the expert on whom I rely."

The expert I rely on negotiates well.
Expertul pe care mă bazez negociază bine.
The colleague he relies on is busy.
Colegul pe care se bazează este ocupat.

Putting It Together

These structures let you fluently connect multiple ideas into a single, precise sentence.

They are organizing a debate about the theme we are referring to.
Ei organizează o dezbatere despre tema la care ne referim.
