Block a view of a certain conversion (9)
I believe the answer is:
'a certain conversion' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'block a view' is the wordplay.
'block' becomes 'dam' (damming is a kind of blocking).
'view' becomes 'scene' (synonyms).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for damascene that I've seen before include "inlaid work" , "ornament" , "Rich ornamentation on metal" , "Syrian" , "Middle Eastern" .)
