I suppose. I just don't hear it as much. In either case, I would think "I'm obligated" should also be an acceptable answer.
Forced is not accepted but it is shown as an accepted translation. What gives?
So does it behave like an adjective? I mean tvungen, tvunget, tvungna. Is there an indefinite form?
Swedish has a number of so-called "strong" verbs - you can find a list and brief explanations here: https://en.wiktionary.org/wiki/Category:Swedish_strong_verbs
Regular verbs are called "weak" because they conform to regular conjugation patterns. And "strong" ones, well, don't.
In fact, tvinga has a younger, weak conjugation pattern as well - you can find both on Wiktionary: https://en.wiktionary.org/wiki/tvinga#Swedish
thank you. you are the best! Tvinga combinations were the most common sentences in my modal verb section.
