Gala, festival (4)
I believe the answer is:
fete
I believe this is a double definition.
'gala' is the first definition.
(I've seen this before)
'festival' is the second definition.
(I know that festival can be written as fete)
(Other definitions for fete that I've seen before include "Wine and dine" , "Outdoor festival" , "Festival; gala" , "Charity garden party" , "Honour lavishly; outdoor function" .)
