Questions & Answers about Moram izaći iz ureda prije šest.
Moram is the 1st person singular present of morati, meaning must or have to.
So:
- moram = I must / I have to
- moraš = you must
- mora = he/she/it must
In this sentence, moram izaći means I have to leave / I must go out.
Croatian often drops subject pronouns when they are not needed.
The ending in moram already tells you the subject is I, so ja is unnecessary.
- Moram izaći. = I have to leave.
- Ja moram izaći. = also possible, but ja adds emphasis, like I have to leave.
So the version without ja is the normal, neutral one.
