Questions & Answers about Chyba zwichnąłem sobie nadgarstek.
Why do we use sobie here instead of saying mój nadgarstek (my wrist)?
This is the dative of inalienable possession. In Polish, when an action happens to your own body part, you usually avoid possessive pronouns like mój. Instead, you use the dative reflexive pronoun sobie (literally "to myself") to indicate whose body part it is and who is experiencing the action.
Could I just say Zwichnąłem nadgarstek and leave out sobie?
Yes, and people would still assume it was your own wrist because of the "I" verb form. However, including sobie emphasizes the "detriment" aspect—it highlights that this unfortunate event happened to you and personally affects you. Using sobie with body parts makes your Polish sound much more natural.
Why is "I think" translated as Chyba rather than Myślę, że?
While Myślę, że zwichnąłem... is grammatically correct, it can sound a bit heavy for a sudden realization. The particle chyba (meaning "probably" or "I guess") is the most common and natural way in conversational Polish to express a strong suspicion or mild uncertainty without needing to build a complex sentence.
