Breakdown of Wieczorem wolę książkę niż telewizję.
Questions & Answers about Wieczorem wolę książkę niż telewizję.
Polish often expresses “in/at [time of day]” just by using a noun in a particular case, without any preposition:
- rano – in the morning
- po południu – in the afternoon
- wieczorem – in the evening
- w nocy – at night (this one keeps the preposition w)
So wieczorem by itself already means “in the evening”. Adding w (w wieczorem) would be incorrect.
Wieczorem is the instrumental singular of wieczór (evening).
Polish often uses the instrumental to express time when something happens. In this adverbial use, wieczorem means “in the evening” and functions like an adverb:
- Rano piję kawę. – I drink coffee in the morning.
- Wieczorem wolę książkę. – In the evening I prefer a book.
You will see many time expressions either in the instrumental (like wieczorem) or in forms that have become fixed adverbs (like rano).
