Some hedging split asunder in part (6)
I believe the answer is:
privet
'some hedging' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'split asunder in part' is the wordplay.
'split asunder' becomes 'rive' (I've seen this in another clue).
'in' is an insertion indicator.
'part' becomes 'pt' (abbreviation).
'rive' placed into 'pt' is 'PRIVET'.
Can you help me to learn more?
(Other definitions for privet that I've seen before include "Hedging shrub" , "Common hedge shrub" , "Let the vet rip up the hedge" , "popular boundary choice" , "hedge material" .)
