Microeconomics: Question on Market for Factors
Nominal means measured in present day money. E.g. someone in South Africa may have a monthly salary of 100,000 South African Rands. You have no idea how much this is unless you are told what real goods can be purchased from this. If a TV costs 10,000 Rands then the real wage of this person would be 10 TVs. Now you see the difference between nominal wages and real wages. 

If you reread your question focusing on this part: "The Wage(in terms of good we produce)" I hope all your confusion will go away.
