"We were treated well."
Translation:Vi blev väl behandlade.
The passive voice in Swedish is formed in one of four ways:
add an -s to the infinitive form of the verb
use a form of bli (become) + the perfect participle
use a form of vara (be) + the perfect participle
use a form of få (get) + the perfect participle
Of the first three forms, the first (s-passive) tends to focus on the action itself rather than the result of it. The second (bli-passive) stresses the change caused by the action. The third (vara-passive) puts the result of the action in the centre of interest:
Dörren målas. (Someone paints the door right now.)
Dörren blir målad. (The door is being painted, in a new colour or wasn't painted before.)
Dörren är målad. (The door is painted.)
