German boy taking green fruit around (4)
I believe the answer is:
emil
'german boy' is the definition.
(I've seen this before)
'green fruit around' is the wordplay.
'green fruit' becomes 'lime' (I've seen this before).
'around' says the letters should be written in reverse.
'lime' backwards is 'EMIL'.
'taking' is the link.
(Other definitions for emil that I've seen before include "- - Zatopek, Olympic runner" , "French boy's name" , "German boy" .)
