One who bargains with witch initially greeting the French ringleader (7)
I believe the answer is:
haggler
'one who bargains' is the definition.
The definition suggests a singular noun which matches the answer.
'witch initially greeting the french ringleader' is the wordplay.
'witch' becomes 'hag' (synonyms).
'initially' says to take the initial letters.
'the french' becomes 'le' ('the' in French).
'ringleader' becomes 'r' (first letter of ring).
The first letter of 'greeting' is 'g'.
'hag'+'g'+'le'+'r'='HAGGLER'
'with' is the link.
Can you help me to learn more?
(Other definitions for haggler that I've seen before include "One arguing over price" , "One bargains on price" , "Dealer" , "One seeking bargain" , "One trying to get price reduced" .)
