British risk losing good fruit plant (7)
I believe the answer is:
bramble
'losing good fruit plant' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'british risk' is the wordplay.
'british' becomes 'br' (abbreviation for British).
'risk' becomes 'amble' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'br'+'amble'='BRAMBLE'
Can you help me to learn more?
(Other definitions for bramble that I've seen before include "Wild thorny shrub" , "Source of fruit" , "Blackberry shrub" , "Briar" , "Thorny bush" .)
