Festival just passable (4)
I believe the answer is:
fair
I believe this is a triple definition!
'festival' is the first definition.
(thesaurus)
'just' is the second definition.
(just can mean fair in the sense of showing justice)
'passable' is the third definition.
(synonyms)
(Other definitions for fair that I've seen before include "Where the helter-skelter may be" , "Having light-coloured hair and skin" , "Unbiased, being light of skin" , "Blonde; beautiful" , "Show - just - lovely" .)
