Distinct atmosphere (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
aura
'distinct atmosphere' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aura that I've seen before include "Particular ambience" , "'Air, atmosphere (4)'" , "Intangible quality surrounding a person or thing" , "Air, distinctive quality" , "Vibe" .)
