With company in, a worrier turned kind of green (3-7)
I believe the answer is:
eco-warrior
'green' is the definition.
(I've seen this before)
'with company in a worrier turned kind of' is the wordplay.
I cannot really see how this works, but
'with' could be 'w' (abbreviation) and 'w' is located in the answer.
'company' could be 'co' (abbreviation) and 'co' is found within the answer.
'a' is within the answer.
'of' could be 'o' and 'o' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for eco-warrior that I've seen before include "Militant greenie" , "Activist" , "Zealous environmentalist" .)
