Po przerwie uczymy się dalej.

Because Polish nouns change form depending on their grammatical role. After po in this sentence, przerwa takes the locative form, so it becomes przerwie.

So:

• dictionary form: przerwa
• after po here: po przerwie

This is a very common pattern in Polish.

Here it is locative.

That is a good question, because for many feminine nouns ending in -a, the dative singular and locative singular look identical. So przerwie could be either in form, but the preposition tells you what it is.

In po przerwie, the preposition po means after, and in this use it requires the locative.

Because uczyć and uczyć się are different verbs.

• uczyć = to teach
• uczyć się = to learn / to study

So:

• uczymy = we teach
• uczymy się = we learn / we study

In this sentence, się is not best understood as ourselves. It is part of the verb uczyć się.

It is the present tense, first person plural form of uczyć się.

Breakdown:

• uczyć się = infinitive
• uczymy się = we learn / we are learning / we study

The ending -my shows we.

Because Polish present tense can cover both a general meaning and a current action, uczymy się can mean:

• we learn
• we are learning
• we study

The exact meaning depends on context.

Here dalej means something like further, on, or continuing.

In this sentence it gives the idea that the action continues after the break. So it is similar to:

• we keep learning
• we continue studying
• we go on learning

Without dalej, the sentence would still be grammatical, but the idea of continuation would be less explicit.

Because in Polish, the verb ending usually already tells you who the subject is.

In uczymy się, the ending -my means we, so the pronoun my is not necessary.

Polish often leaves subject pronouns out unless they are needed for:

• emphasis
• contrast
• clarity

For example:

• Po przerwie uczymy się dalej. = normal, neutral
• Po przerwie my uczymy się dalej. = we keep learning, maybe in contrast to someone else

Yes. Polish word order is fairly flexible.

Po przerwie uczymy się dalej is a natural sentence, with po przerwie placed first to set the time frame: after the break.

Other orders are possible, for example:

• Uczymy się dalej po przerwie.
• Po przerwie dalej się uczymy.

The basic meaning stays similar, but the emphasis changes. Polish word order is often used to highlight what is most important or most topical in the sentence.

Usually it suggests after the break, often in a fairly direct, practical sense, especially in contexts like school or a lesson schedule. But the phrase itself does not strictly guarantee immediately.

If the context is a classroom, most people will naturally understand it as once the break is over, we continue. The exact timing comes more from context than from the grammar alone.
