Questions & Answers about Wieczorem patrzymy na świecącą latarnię i na małe migające gwiazdy.

What does Wieczorem literally mean, and why does it end with -em?

Wieczorem literally means “in the evening / at evening time.”

Grammatically:

• The basic noun is wieczór – evening (nominative).
• Wieczorem is the instrumental singular form of wieczór.

Polish very often uses the instrumental case (without a preposition) to talk about time when something happens:

• wieczorem – in the evening
• rano / rankiem – in the morning
• nocą – at night
• latem – in (the) summer

So instead of saying something like “w wieczór” (in the evening), Polish normally just uses Wieczorem as a kind of time adverbial:
Wieczorem patrzymy… = In the evening we look…
