Questions & Answers about Agentul așteaptă aici.
Because -ul is the Romanian definite article attached to the end of a masculine singular noun.
- agent = agent
- agentul = the agent
Romanian usually puts the at the end of the noun instead of using a separate word like English does.
Compare:
- un agent = an agent
- agentul = the agent
Așteaptă is the present tense form of the verb a aștepta = to wait.
In this sentence, it goes with agentul, so it means:
- the agent waits
- or the agent is waiting
A useful mini-conjugation:
- eu aștept = I wait / am waiting
- tu aștepți = you wait / are waiting
- el/ea așteaptă = he/she waits / is waiting
- noi așteptăm = we wait / are waiting
- voi așteptați = you all wait / are waiting
- ei/ele așteaptă = they wait / are waiting
Notice that așteaptă can also be they wait, but in your sentence the subject agentul is singular, so here it is clearly he/she waits.
