Questions & Answers about Wieczorem lubię śpiewać w kuchni.

Why is it wieczorem and not wieczór?

Both come from the noun wieczór (evening), but they are different grammatical forms.

• wieczór – nominative (dictionary form), used mainly as the subject or object:
  
  • Ten wieczór jest zimny. – This evening is cold.
• wieczorem – instrumental, very often used as an adverbial expression of time:
  
  • Wieczorem czytam książki. – In the evening I read books.

Polish often uses the instrumental case to express “when” something happens (especially parts of the day):

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

So Wieczorem lubię śpiewać… literally is “In-the-evening I-like to-sing…”, and wieczorem is the natural, idiomatic form here. Using wieczór without a preposition in this position would be incorrect.

Could I say „Lubię śpiewać w kuchni wieczorem” instead? Is that still correct?
