Said you entered a government territory with an effigy (6)
I believe the answer is:
statue
'an effigy' is the definition.
(I've seen this before)
'said you entered a government' is the wordplay.
'said you' becomes 'u' (I've seen this in other clues. I am not sure about the 'said' bit.).
'entered' means one lot of letters goes inside another.
'a government' becomes 'state' (state is a kind of government).
'u' inserted inside 'state' is 'STATUE'.
'territory with' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for statue that I've seen before include "Carved representation" , "Sculpture depicting a person" , "See figure" , "A carved or sculpted figure" , "Monument" .)
