Pinpoint fine tidy ground (8)
I believe the answer is:
identify
'pinpoint' is the definition.
(I've seen this before)
'fine tidy ground' is the wordplay.
'ground' is an anagram indicator (grind the letters ).
'fine'+'tidy'='finetidy'
'finetidy' with letters rearranged gives 'IDENTIFY'.
(Other definitions for identify that I've seen before include "Recognise as specific person or thing" , "Establish who a person is" , "Empathise" , "Recognise, put name to" , "Sympathise" .)
