Questions & Answers about Dok trčimo u parku, ponekad nas boli noga ili ruka.
What does dok mean here, and could I use kad instead?
Dok means while / as and emphasizes that two actions are happening at the same time:
- Dok trčimo u parku, ponekad nas boli noga ili ruka.
= While we are running in the park, sometimes our leg or arm hurts.
Kad can mean when in both a general/habitual sense and a one-time event. In this sentence:
- Kad trčimo u parku, ponekad nas boli noga ili ruka.
is also possible and natural, and sounds more like a general condition: When(ever) we run in the park, sometimes our leg or arm hurts.
Nuance:
- dok → focuses more on simultaneity (during the running)
- kad → more on condition or time in general (whenever we run)
Why is trčimo just a simple present tense, when in English we say “are running”?
Croatian does not have a special continuous/progressive tense like English (are running, is going). The present tense usually covers both:
- trčimo = we run / we are running
So Dok trčimo u parku naturally means While we are running in the park, even though it’s just a plain present tense form in Croatian (1st person plural).
What is the role of u parku, and could I say na parku or po parku instead?
