Speak for the nation? (5)
I believe the answer is:
state
This clue is a double definition.
'speak' is the first definition.
(I've seen this in another clue)
'nation' is the second definition.
(I know that nation can be written as state)
'for the' acts as a link.
(Other definitions for state that I've seen before include "Part of America" , "Specify condition" , "Government; say" , "Speak" , "Declare; affirm" .)
