Questions & Answers about Hon gråter därför att hon är besviken.
Can I use eftersom instead of därför att in this sentence?
Yes, you can! Both mean 'because' and can connect these two clauses. However, därför att is a great choice here because it is mostly used when the reason comes in the second half of the sentence and introduces new information to the listener.
Could I flip the sentence around and start it with Därför att hon är besviken...?
No, you cannot start a sentence with därför att. If you want to put the reason at the very beginning of the sentence, you must use eftersom instead: Eftersom hon är besviken gråter hon.
What happens if I leave out att and just use därför?
By itself, därför means 'therefore', which is an adverb, not a conjunction. To say 'because', you need the full phrase därför att. If you just used därför, you would have to change the logic of the sentence entirely: Hon är besviken, därför gråter hon (She is disappointed, therefore she is crying).
Why does the adjective end in '-en' (besviken) instead of '-et' or '-na'?
Adjectives in Swedish change their ending to match the noun they describe. Here, the adjective describes hon (she), which follows the standard en-word rules, so we use the basic form besviken. If it were an ett-word like barnet (the child), it would be besviket, and if it were plural like de (they), it would be besvikna.
