Fresher environment reportedly (6)
I believe the answer is:
airier
'fresher' is the definition.
Both the definition and answer are comparative adjectives. Maybe there's a link between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for airier that I've seen before include "More spacious and better ventilated" , "More dismissive" , "Breezier" .)
