Garden party originally for everyone to enjoy
I believe the answer is:
fete
'garden party' is the definition.
(I've seen this in another clue)
'originally for everyone to enjoy' is the wordplay.
'originally' indicates taking the first letters.
The initial letters of 'for everyone to enjoy' is 'FETE'.
(Other definitions for fete that I've seen before include "Marilyn Monroe's real first name' constellation" , "Festival, fiesta" , "Outdoor entertainment run for charity" , "Entertain regally" , "Lavishly entertain; charity function" .)
