Questions & Answers about Ostajem ovde zauvek.
Because Serbian often drops subject pronouns when they are already clear from the verb ending.
Ostajem ends in -m, which tells you the subject is I. So Ostajem ovde zauvek is perfectly complete without ja.
You can add ja for emphasis or contrast:
- Ja ostajem ovde zauvek. = I’m staying here forever.
That can sound more emphatic, as if contrasting with someone else.
The base form is ostajati, which is an imperfective verb.
So:
- ostajati = to stay, to remain
- ostajem = I stay / I am staying / I’m remaining
In this sentence, ostajem is 1st person singular present tense.
