Moving to a greener part of plantation (6,4)
I believe the answer is:
orange tree
'plantation' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'moving to a greener' is the wordplay.
'moving' indicates anagramming the letters (letters are moved around).
'to'+'a'+'greener'='toagreener'
'toagreener' with letters rearranged gives 'ORANGE-TREE'.
'part of' is the link.
Can you help me to learn more?
(Other definitions for orange tree that I've seen before include "Jaffa-bearing growth" , "orchard feature" .)
