Wieczorem układamy puzzle przy stole, bo nasza córka bardzo je lubi.

Wieczorem is a very common Polish adverbial form meaning in the evening / during the evening.

In Polish, parts of the day are often expressed this way:

• rano — in the morning
• wieczorem — in the evening
• nocą — at night

So Wieczorem układamy puzzle... means In the evening, we do/put together puzzles...

You do not normally say w wieczór here.

Układamy is the 1st person plural form of układać, so it means we arrange / we put together / we lay out.

With puzzle, układać puzzle is the normal expression for:

• to do a jigsaw puzzle
• to put a puzzle together

So even though the literal sense is something like we arrange puzzles, the natural English meaning is we do puzzles or we put puzzles together.

Because the infinitive is układać, and its present-tense conjugation is:

• układam — I put together
• układasz — you put together
• układa — he/she/it puts together
• układamy — we put together
• układacie — you all put together
• układają — they put together

So układamy simply means we put together.

Polish often leaves out subject pronouns when they are already clear from the verb ending.

• układamy already tells you the subject is we
• lubi already tells you the subject is he/she/it

So:

• (My) układamy puzzle = We do puzzles
• nasza córka bardzo je lubi = our daughter likes them very much

You can add my for emphasis, but it is usually unnecessary.

Puzzle is a borrowed noun from English. In Polish, it is commonly treated as a plural-only noun when talking about a jigsaw puzzle.

So:

• układać puzzle — to do a puzzle / to do puzzles
• lubić puzzle — to like puzzles

In this sentence, puzzle is the direct object of układamy, and its form stays puzzle.

Przy stole means at the table or by the table.

The preposition przy is used when someone is positioned near something, often while using it:

• siedzieć przy stole — to sit at the table
• jeść przy stole — to eat at the table
• układać puzzle przy stole — to do puzzles at the table

By contrast:

• na stole means on the table

So:

• Puzzle leżą na stole — The puzzles are lying on the table
• Układamy puzzle przy stole — We are doing puzzles at the table

Because przy requires the locative case.

The noun stół changes like this:

• nominative: stół — table
• locative: stole — at/on the table (after certain prepositions)

So:

• przy stole — at the table
• na stole — on the table

This is a case change caused by the preposition.

Yes. Bo means because.

It is very common in everyday spoken and written Polish:

• Zostaję w domu, bo pada. — I’m staying home because it’s raining.
• Układamy puzzle, bo nasza córka bardzo je lubi. — We do puzzles because our daughter likes them very much.

A slightly more formal alternative is ponieważ.

So:

• bo — because, common and conversational
• ponieważ — because, a bit more formal

Because nasza córka is the subject of the second clause:

• nasza córka bardzo je lubi — our daughter likes them very much

Subjects are normally in the nominative case:

• nasza córka — our daughter

If our daughter were the object, then you would use a different case:

• Widzę naszą córkę. — I see our daughter.

So here:

• nasza córka = subject, nominative
• naszą córkę = object, accusative

Je means them here, and it refers to puzzle.

So:

• nasza córka bardzo je lubi
• literally: our daughter likes them very much

This is a direct-object pronoun in the accusative.

Because lubić takes a direct object in the accusative case, and the accusative pronoun for them (non-masculine-personal) is je.

So:

• Lubi puzzle. — She likes puzzles.
• Bardzo je lubi. — She likes them very much.

Ich is often used in other roles, especially genitive, and can also sometimes appear in colloquial speech, but in standard grammar here je is the expected form.

In Polish, short unstressed object pronouns such as go, ją, je, mi, ci often come before the verb.

So:

• bardzo je lubi — she likes them very much

This placement is very natural in Polish.

You may sometimes see different word orders for emphasis, but je lubi is the most neutral here.

Because the subject is nasza córka — our daughter, which is singular.

The verb lubić in the present tense goes like this:

• lubię — I like
• lubisz — you like
• lubi — he/she/it likes
• lubimy — we like
• lubicie — you all like
• lubią — they like

So:

• nasza córka lubi — our daughter likes
• nasze córki lubią — our daughters like

Bardzo means very.

So:

• bardzo je lubi — she likes them very much

It strengthens the verb lubi.

Other examples:

• bardzo lubię kawę — I like coffee very much
• bardzo dobrze — very well
• bardzo ładny — very pretty

In real usage, układać puzzle often means to do a jigsaw puzzle, even though the form looks plural.

So depending on context, English might translate it as:

• We do a jigsaw puzzle in the evening...
• We do puzzles in the evening...

Polish commonly uses puzzle in this plural-looking form for the activity in general.

Yes. Polish word order is more flexible than English, although each version may sound slightly different in emphasis.

For example:

• Wieczorem układamy puzzle przy stole, bo nasza córka bardzo je lubi. — neutral
• Przy stole układamy wieczorem puzzle... — stronger focus on at the table
• Nasza córka bardzo lubi je. — possible, but less natural than bardzo je lubi

The original sentence has a very natural, neutral word order.

Układać is imperfective.

That fits well because the sentence describes a repeated or habitual activity:

• Wieczorem układamy puzzle... — In the evening we do puzzles / we put a puzzle together

Imperfective verbs are commonly used for:

• repeated actions
• ongoing actions
• general habits

The perfective partner would be ułożyć, which is more about completing something:

• ułożymy puzzle — we will complete the puzzle / put the puzzle together

So układamy is the right choice for a regular evening activity.
