Indication given to a head of state for delegate (6)
I believe the answer is:
assign
'delegate' is the definition.
('assign' can be a synonym of 'delegate')
'indication given to a head of state' is the wordplay.
'indication' becomes 'sign' (I've seen this before**).
'given to' says to put letters next to each other.
'head of' says to take the initial letters.
The initial letter of 'state' is 's'.
'a'+'s'='as'
'sign' put after 'as' is 'ASSIGN'.
'for' is the link.
(Other definitions for assign that I've seen before include "Apportion, ascribe" , "Allot, allocate" , "Select and appoint for task" , "award" , "Allocate or transfer" .)
