Have the teeniest bit of broth, do (7)
I believe the answer is:
soupcon
'have the teeniest bit' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'broth do' is the wordplay.
'broth' becomes 'soup' (I've seen this before).
'do' becomes 'con' (both can mean to defraud).
'soup'+'con'='SOUPCON'
'of' is the link.
Can you help me to learn more?
(Other definitions for soupcon that I've seen before include "Very tiny amount" , "Dash" , "A vary small quantity, just a trace - from France" , "A very small quantity, from French" , "Hint" .)
