I want to translate the phrase
Finder will be rewarded.
to German. Somehow there is no dictionary on the net which contained the phrase. I am looking for a metaphorical equivalent.
You could just remark Finderlohn!
If you know, what you want to pay, you could combine it with the sum you want to pay.
In German you use a noun for this: Finderlohn.
Im ganzen Satz:
Dem Finder winkt eine Belohnung.
Some languages have words where other languages need whole sentences for.
In Germany we say "Finderlohn" which means "Reward for the finder".
