Questions & Answers about Ne žurim se jer imamo još vremena.
Žurim is the 1st person singular present tense form of žuriti se. It means I hurry / I am hurrying / I am in a hurry, depending on context.
In Croatian, the present tense often covers both English simple present and present continuous, so Ne žurim se can naturally mean I'm not hurrying or I'm not in a hurry.
Because the verb is normally learned as žuriti se, not just žuriti.
Here, se is not literally myself. It is part of a reflexive verb, and many Croatian verbs work this way. So you should think of žuriti se as a single unit meaning to hurry / to be in a hurry.
Usually, no—not if you want the meaning I'm not hurrying / I'm not in a hurry.
The natural form is žuriti se. Without se, the sentence sounds incomplete or unnatural for this meaning.
