Questions & Answers about Die Eisenbahn wurde früher erfunden.
How do we know this sentence is in the passive voice?
The combination of wurde (the simple past of werden) in the second position and the past participle erfunden at the end of the sentence creates the passive voice. Specifically, wurde tells us this is the action passive (Vorgangspassiv) in the past tense, translating to "was invented".
Why doesn't the past participle erfunden have a ge- at the beginning?
The verb erfinden (to invent) starts with the inseparable prefix er-. Verbs with inseparable prefixes (like be-, ent-, er-, and ver-) do not take the ge- prefix when forming the past participle. Therefore, the past participle of erfinden is simply erfunden.
Does früher always mean "earlier"?
Literally, yes; it is the comparative form of früh (early). However, Germans frequently use früher as a general time marker to simply mean "in the past", "formerly", or "back in the day". Depending on the wider context, this sentence could mean the railway was invented "earlier" (before something else, like the car) or just generally "in the past".
Could I say "Die Eisenbahn war früher erfunden" instead of using wurde?
