Questions & Answers about Latem mgła opada po zmierzchu.
Why does this sentence use latem without any prepositions like "in" or "during"?
The word latem is the Instrumental case of lato (summer). In Polish, you can express "in the summer" simply by putting the season into the bare Instrumental case, without needing a preposition. You could also say w lecie (using the Locative case), but using the bare Instrumental is a very common and natural way to talk about seasons and certain times of day.
Why does zmierzch change to zmierzchu here?
It changes to zmierzchu because it follows the preposition po (after). When po is used to mean "after a certain time or event," it requires the following noun to be in the Locative case.
I know the verb padać means "to fall" or "to rain". How does the prefix in opada change the meaning?
While pada is typically used for rain, snow, or a sudden drop, adding a prefix creates opadać, which describes something settling, sinking slowly, or subsiding. This makes it the perfect verb to use for fog, dust, or leaves gently descending from the air.
Is opada an imperfective or perfective verb?
