Section of government -- it leaked name (7)
I believe the answer is:
entitle
'name' is the definition.
(both can mean to give someone a name)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for entitle that I've seen before include "Name; enable" , "Give a right or authority to" , "Style; give right to" , "Allow" , "Furnish with a right or claim" .)
