On winding road it's showing skill (6)
I believe the answer is:
adroit
'skill' is the definition.
(I've seen this before)
'on winding road it's' is the wordplay.
'on' says to put letters next to each other.
'winding' indicates anagramming the letters.
'it's' becomes 'it' (I've seen this in other clues**).
'road' is an anagram of 'adro'.
'adro' put next to 'it' is 'ADROIT'.
'showing' acts as a link.
(Other definitions for adroit that I've seen before include "Apt" , "Quick or adept" , "Quick and clever in action or thought" , "Dextrous" , "Dexterous, artful" .)
