Iffy bishop with request to be served some coke? (10)
I believe the answer is:
borderline
'iffy bishop' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'request to be served some coke?' is the wordplay.
'request' becomes 'order' (an order is a request from someone in authority).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'be served some' becomes 'b' (I can't justify this - if you can you should believe this answer much more).
'coke?' becomes 'line' (a line of cocaine).
'order' after 'b' is 'border'.
'border'+'line'='BORDERLINE'
'with' is the link.
Can you help me to learn more?
(Other definitions for borderline that I've seen before include "frontier" , "divides countries" , "Marginal n" , "Boundary" , "barely acceptable" .)
