i missed the explanation of the difference between se(s) and si(s). Both are reflexive postfixes, equally applicable to all genders, analogous to polish się, right? When do I use which, then?
We explained severall times in the sentence discussions but it is not easy to find. Ultimately it will be governed by the verb whether it is reflexive or not and which one of these it requires. The main difference is whther it is the accusative case or the dative case https://en.wiktionary.org/wiki/se#Declension_2
This should really be asked in the main discussion, not in the sentences. Probavly you willl find older related threads there.
