Frolics in thorny shrubs (6)
I believe the answer is:
capers
This clue could be a double definition.
'frolics' is the first definition.
('caper' can be a synonym of 'frolic')
'thorny shrubs' is the second definition.
'capers' can be an answer for 'shrubs' (caper is a kind of shrub). I am unsure of the 'thorny' bit.
'in' is the link.
Can you help me to learn more?
(Other definitions for capers that I've seen before include "Scrape (anag)" , "Jumps about playfully, or flavouring buds" , "Light-hearted fun" , "Pranks and pickled buds" , "Scrape leading to frolics" .)
