Questions & Answers about U centru je veliki saobraćaj svako jutro.
Because u can take two different cases:
- accusative for movement to/into somewhere: u centar = to the center
- locative for being in a place: u centru = in the center
In this sentence, there is no movement. It describes where the traffic is, so Serbian uses the locative: u centru.
Centru is the locative singular of centar.
The noun changes like this:
- nominative: centar
- locative: centru
After u when it means in, the locative is used, so u centru means in the center / downtown.
This is a normal Serbian way to say that something is present somewhere.
Literally, the structure is close to:
- U centru je veliki saobraćaj.
- In the center is heavy traffic.
English usually prefers There is heavy traffic downtown, but Serbian can simply use je with the noun phrase.
So agrees with , which is singular.
