Fine atmosphere for outdoor entertainment (4)
I believe the answer is:
fair
'outdoor entertainment' is the definition.
'fair' can be an answer for 'entertainment' (as in a fun fair). I'm not certain of the 'outdoor' bit.
'fine atmosphere' is the wordplay.
'fine' becomes 'f' (abbreviation e.g. condition of old coins, books).
'atmosphere' becomes 'air' (synonyms).
'f'+'air'='FAIR'
'for' is the link.
Can you help me to learn more?
(Other definitions for fair that I've seen before include "Free from discrimination" , "Just; beautiful; blond" , "Equitable ? - trade show" , "Trade exhibition, (of weather) fine" , "Where the helter-skelter may be" .)
