Shade inexperienced (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
green
This clue is a double definition.
'shade' is the first definition.
(I know that Green is a type of shade)
'inexperienced' is the second definition.
(similar in meaning)
(Other definitions for green that I've seen before include "Genre (anag.)" , "member of political party" , "Putting area" , "Environmental - colour" , "Flourishing" .)
