More bananas in dish consumed by ladies, say, and queen (7)
I believe the answer is:
loopier
'more bananas' is the definition.
(bananas can mean loopy or mad)
'dish consumed by ladies say and queen' is the wordplay.
'dish' becomes 'pie' (I've seen this before).
'consumed by' is an insertion indicator (inserted letters get consumed).
'ladies say' becomes 'loo' (ladies toilet).
'and' says to put letters next to each other.
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'loo'+'r'='loor'
'pie' put within 'loor' is 'LOOPIER'.
'in' is the link.
(Other definitions for loopier that I've seen before include "More crazy" , "less stable" , "more unbalanced" , "Dafter" .)
