Questions & Answers about Wieczorem siedzę z mamą na balkonie i pijemy herbatę.

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

Polish doesn’t usually say w wieczór.
The noun wieczór (evening) takes a special form wieczorem, which is historically the instrumental case but in practice works like an adverb of time: wieczorem = in the evening / this evening.

Polish uses similar forms for time expressions:

• latem – in (the) summer
• zimą – in (the) winter
• nocą – at night

So Wieczorem siedzę… literally is “(I) sit in the evening…”, and that’s the natural way to say it. Using w wieczór would sound wrong or very odd.

Does this sentence mean a habitual action (“In the evenings I usually do this”) or something happening this evening?

It can mean either, depending on context.

By default, Wieczorem siedzę z mamą na balkonie i pijemy herbatę. is often understood as a habitual action:

• In the evening I (usually) sit with my mom on the balcony and we drink tea.

But in the right context it can also refer to today’s evening:

• e.g. answering Co dziś robisz? (What are you doing today?) – Wieczorem siedzę z mamą na balkonie i pijemy herbatę. → This evening I’m going to sit with my mom on the balcony and we’ll drink tea.

Polish present tense of imperfective verbs covers both “I do” and “I am doing / I will be doing (this evening)” depending on adverbs and context.
