Questions & Answers about Mi rijetko izlazimo navečer.
That is true: Croatian often leaves out subject pronouns because the verb ending already shows who is doing the action.
Here, izlazimo already means we go out / we are going out, so mi is not strictly necessary.
- Rijetko izlazimo navečer. = perfectly normal
- Mi rijetko izlazimo navečer. = adds a bit of emphasis, contrast, or clarity
Using mi can suggest something like:
- we rarely go out in the evening
- as for us, we rarely go out in the evening
So mi is optional here, but natural.
Rijetko is an adverb meaning rarely.
It tells you how often the action happens. In this sentence, it modifies izlazimo.
Croatian often places frequency adverbs like rijetko, često, ponekad, uvijek before the verb:
- rijetko izlazimo
- često putujem
- uvijek radi
So rijetko izlazimo = we rarely go out.
