"Does Worf live in First City?"
Translation:veng wa'DIch Dab'a' wo'rIv?
Are you referring to the Klingon sentence, and do you mean "preposition" rather than "adjective"?
The verb Dab means something like "inhabit" or "live in". It simply takes a direct object (the place which you inhabit) and does not need the ending -Daq.
For example, tera' vIDab "I inhabit the Earth. I live on Earth."
