"His vehicle is old."
Translation:Sein Fahrzeug ist alt.
Would, "Er Fahrzeug ist alt" be an acceptable answer, i used the option to pick from the words given and didn't use Er as it wasn't there.
Could someone help explain if that would be correct, or if not, why would is it "Sein"
Er = He and Sein = His. You want to say "His vehicle is old", not "He vehicle is old".
Sidenote - Sein is used here because Fahrzeug is neuter. "His" is translated to "Sein" for masculine and neuter nouns, but "His" is translated to "Seine" for feminine nouns.
So for a feminine noun you would say - "Seine bank ist alt"
Is it normal to use "Vehicle" instead of "Car" on daily basis in Germany ?
"Sein Gefährt ist alt" worked for me.
By the way, you want to make sure you say "his vehicle" (Sein Gefährt) not "a vehicle" (ein Gefährt), because the vehicle belongs to a male person.
