Questions & Answers about 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.
