Where many a skill is used in trading (4)
I believe the answer is:
mart
'used in trading' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'where many a skill' is the wordplay.
'where many' becomes 'm' (Roman numeral for a thousand. I am not sure about the 'where' bit.).
'a skill' becomes 'art' (both can mean a talent).
'm'+'art'='MART'
'is' is the link.
Can you help me to learn more?
(Other definitions for mart that I've seen before include "Place" , "Take tram to market" , "US shop; market" , "Trading centre" .)
