A little fruit Romeo traded, pocketing £50 (7)
I believe the answer is:
morello
'a little fruit' is the definition.
'morello' can be an answer for 'fruit' (morello is a kind of fruit). I'm not sure about the 'a little' bit.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for morello that I've seen before include "Small, dark, sour cherry" , "Type of cherry" , "Sour red fruit" , "Dark-red variety of cherry" , "Sour cherry tree" .)
