Make row outside back of market, getting more bananas (7)
I believe the answer is:
dottier
'getting more bananas' is the definition.
I can't judge whether this definition defines the answer.
'make row outside back of market' is the wordplay.
'make' becomes 'do' (do can mean to make or prepare).
'row' becomes 'tier' (a tier is a row of things).
'outside' means one lot of letters goes inside another (some letters go outside others).
'back of' indicates one should take the final letters.
The last letter of 'market' is 't'.
'tier' enclosing 't' is 'ttier'.
'do'+'ttier'='DOTTIER'
Can you help me to learn more?
(Other definitions for dottier that I've seen before include "Detroit (anag) - more eccentric" , "Crazier" , "less rational" , "more absurd" , "with even less reason" .)
