Questions & Answers about Wieczorem często wspominam wakacje nad morzem.

Why is it wieczorem and not w wieczór for “in the evening”?

Polish usually uses the instrumental case without a preposition to express “in the [part of the day / time]”:

• rano – in the morning
• po południu – in the afternoon
• wieczorem – in the evening
• nocą – at night

Wieczorem is the instrumental form of wieczór and functions like an adverb of time.
Saying w wieczór is not natural in modern Polish in this meaning.

Can I change the word order and say Często wieczorem wspominam wakacje nad morzem?

Yes. Both are correct:

• Wieczorem często wspominam…
• Często wieczorem wspominam…

Word order in Polish is flexible. The difference is mostly about rhythm and emphasis:

• Wieczorem często… slightly emphasizes the time (“in the evening”) first.
• Często wieczorem… slightly emphasizes frequency (“often”) first.

Both will be understood the same in normal conversation.

Why is the verb wspominam used here and not something like pamiętam?
