On a winding road it is showing skill (6)
I believe the answer is:
adroit
'showing skill' is the definition.
'adroit' can be an answer for 'skill' (I've seen this before). I'm not sure about the 'showing' bit.
'on a winding road it' is the wordplay.
'on' means one lot of letters go next to another.
'a winding' is an anagram indicator.
'road' with letters rearranged gives 'adro'.
'adro' next to 'it' is 'ADROIT'.
'is' is the link.
Can you help me to learn more?
(Other definitions for adroit that I've seen before include "Clever - crafty" , "Skilful, expert" , "Nimble and skilful" , "Skilled" , "Quick or skilful" .)
