Questions & Answers about Es ist deine Pflicht, die Kinder pünktlich abzuholen.
What does the initial Es do here? Is it necessary?
It’s a dummy/anticipatory subject (an expletive). German often uses Es with copular sentences like Es ist …. You can rephrase to focus on the predicate: Deine Pflicht ist es, die Kinder pünktlich abzuholen. But you can’t just drop it and say “Ist deine Pflicht …” in standard German.
Why is it deine Pflicht and not deiner Pflicht?
With sein (to be), both sides are in the nominative (predicate nominative). So it’s nominative feminine singular: die Pflicht → deine Pflicht, not dative (deiner Pflicht). Compare: Es ist dein Buch.
Why deine and not dein?
Because Pflicht is feminine. Possessive determiners agree with the noun’s gender, number, and case. Nominative feminine adds -e: deine Pflicht; nominative masculine/neuter would be dein Vater / dein Kind.
Is the comma before die Kinder pünktlich abzuholen required?
Yes. The infinitive group depends on a noun (Pflicht), so the comma is mandatory. Without the noun trigger, commas with “zu”-infinitives are often optional, but here they’re required.
