Questions & Answers about Das Datum darf noch nicht veröffentlicht sein.
Why do we use sein here instead of werden for the passive?
This sentence uses the state passive (Zustandspassiv), which describes a condition or state of being after an action has been completed. It focuses on the result (the date being in an unpublished state). If we used werden for the process passive (Vorgangspassiv), the sentence Das Datum darf noch nicht veröffentlicht werden would mean the actual action of publishing the date is not allowed to happen yet.
Why is darf noch nicht translated as "must not yet" instead of "doesn't have to yet"?
In German, nicht dürfen means "must not" or "to not be allowed to". It expresses a strict prohibition. If you wanted to say "doesn't have to" to express a lack of obligation, you would use nicht müssen. Here, it means the date is strictly forbidden to be in a published state right now.
Why doesn't the past participle veröffentlicht have a ge- prefix?
Verbs that begin with an inseparable prefix, like ver-, be-, ent-, or er-, never take the ge- prefix when forming the past participle. Since the infinitive veröffentlichen starts with ver-, its past participle remains veröffentlicht.
Why are both veröffentlicht and sein at the very end of the sentence?
