The German word 'geboren' is the past participle of the verb 'gebären', which means 'to give birth'. It is used in the context of describing the birth of a person, for example, 'Ich bin in Berlin geboren' (I was born in Berlin). It can also be used in the passive voice, for example, 'Er wurde am 10. Mai 1990 geboren' (He was born on May 10, 1990).
I was born in Germany.
The verb 'geboren' applies to a past event, the birth, and is combined with the pronoun 'ich' and the preposition 'in' to indicate the location 'Deutschland'.
He was born here.
This sentence uses the third person singular 'er', combined with 'ist' and 'geboren' to express a past event. 'Hier' is used to show the place of birth.
When were you born?
In German, questions about time use 'wann'. The verb 'wurdest' is the second person singular past tense of 'werden', and 'du' refers to the person being asked.
