Party for some legal advocates (4)
I believe the answer is:
gala
'party' is the definition.
(I know that party can be written as gala)
'some legal advocates' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'GALA' can be found hidden inside 'legal advocates'.
'for' acts as a link.
(Other definitions for gala that I've seen before include "Sports meeting" , "Special sports event" , "Jamboree" , "Public party" , "Swimming competition" .)
