Questions & Answers about Jag hinner inte hämta honom vid stationen idag.
hinna is about having enough time (or managing in time). So Jag hinner inte… means you won’t have time / won’t make it in time to do the action.
- Jag kan inte… = you can’t (ability/permission/circumstances), not necessarily time-related.
- Jag orkar inte… = you don’t have the energy (tiredness, motivation).
In this sentence, hinner signals a time constraint: you won’t manage to pick him up today.
After some verbs—especially verbs that behave a bit like modals (including hinna)—Swedish commonly uses a bare infinitive (infinitive without att).
So hinner inte hämta is the natural construction.
Using att here would sound wrong in standard Swedish.
