Abandoned ring found in winding lane (5)
I believe the answer is:
alone
'abandoned' is the definition.
(I've seen this in another clue)
'ring found in winding lane' is the wordplay.
'ring' becomes 'O' (letter resembling a ring).
'found in' is an insertion indicator.
'winding' indicates anagramming the letters.
'lane' is an anagram of 'alne'.
'o' inserted into 'alne' is 'ALONE'.
(Other definitions for alone that I've seen before include "Isolated; exclusively" , "Exclusively; solitary" , "Without others being involved" , "Unaccompanied" , "Singly" .)
