Questions & Answers about Ljeti šetamo s prijateljima u parku.
Why do we use the word ljeti instead of just saying u ljetu for 'in the summer'?
Ljeti is a special adverb used specifically to mean 'in the summertime' or 'during summer'. While u ljetu is grammatically possible, Croatian strongly prefers the fixed adverb ljeti when talking about things you do during that season. You will see a similar pattern for winter (zimi).
Could I use hodamo instead of šetamo for 'we walk'?
You could, but it changes the vibe. Hodati refers to the physical action of walking or getting from point A to point B on foot. Šetati means to take a leisurely stroll or walk for pleasure. Since the context is hanging out with friends in a park, šetamo is the natural choice.
Why is the ending -ima used in s prijateljima?
This is a refresher on the plural Instrumental case. The preposition s (when it means 'together with' someone) requires the noun to be in the Instrumental case. For the masculine noun prijatelj (friend), the plural Instrumental suffix is -ima.
