Endlessly ask the advice of a government official (6)
I believe the answer is:
consul
'advice of a government official' is the definition.
'consul' can be an answer for 'official' (consul is a kind of official). I'm unsure of the 'advice of a government' bit.
'endlessly ask' is the wordplay.
'endlessly' means to remove the last letter.
'ask' becomes 'consult' (consulting is a kind of asking).
'consult' with its final letter removed is 'CONSUL'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for consul that I've seen before include "Old Roman official" , "Official representative of a state living abroad" , "National representative in a foreign city" , "The diplomat deals with commercial matters" , "Diplomat abroad" .)
