Declare, proclaim (8)
I believe the answer is:
announce
I believe this clue is a double definition.
'declare' is the first definition.
(I know that declare can be written as announce)
'proclaim' is the second definition.
(I've seen this in another clue)
(Other definitions for announce that I've seen before include "Declare, proclaim" , "Make known officially" , "Broadcast (information)" , "Declare her weight" , "Make public statement, proclaim" .)
