Economist who creates barriers? (4,5)
I believe the answer is:
adam smith
'economist' is the definition.
(18th-century economist)
'creates barriers?' is the wordplay.
I cannot really understand how this works, but
'barriers?' could be 'dams' (dam is a kind of barrier) and 'dams' is present in the answer.
This explanation may well be incorrect...
'who' acts as a link.
Can you help me to learn more?
(Other definitions for adam smith that I've seen before include "Economist" , "The Wealth of Nations author" , "Moral philosopher" , "Advocate of free trade" .)
