After regrowth, last pair snip edges of privet so that it will flourish (6)
I believe the answer is:
thrive
'flourish' is the definition.
(I know that flourish can be written as thrive)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for thrive that I've seen before include "Grow strongly" , "Prosper, grow well" , "Succeed" , "Hit rev in order to prosper" , "Boom" .)
