Able to hold the road when it’s skiddy – very nice (8)
I believe the answer is:
adorable
'it's skiddy very nice' is the definition.
I can't judge whether this definition defines the answer.
'able to hold the road' is the wordplay.
'to hold' is an insertion indicator.
'the road' becomes 'dora' (I can't explain this - if you can you should believe this answer much more).
'able' enclosing 'dora' is 'ADORABLE'.
'when' acts as a link.
Can you help me to learn more?
(Other definitions for adorable that I've seen before include "Evoking love and admiration" , "Winsome" , "Worthy of worship" , "Endearing" , "Lovely and attractive" .)
