Cop abroad in garden nobbled me (8)
I believe the answer is:
gendarme
'cop' is the definition.
(I've seen this before)
'abroad in garden nobbled me' is the wordplay.
I cannot really see how this works, but
an anagram of 'garden' is 'gendar' which is within the answer.
'me' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for gendarme that I've seen before include "French officer - merge DNA (anag)" , "alpine pinnacle" , "French police officer" , "Law enforcer" , "Busy" .)
