Plantation is wrong of the others (6)
I believe the answer is:
forest
'plantation' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'wrong of the others' is the wordplay.
'wrong' indicates anagramming the letters.
'the others' becomes 'rest' (eg the rest of a group).
'of' anagrammed gives 'fo'.
'fo'+'rest'='FOREST'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for forest that I've seen before include "New, Epping or Sherwood" , "green area" , "See 15" , "Large wood" , "Large area of trees and undergrowth" .)
