European lands boundlessly managed locking up gold (8)
I believe the answer is:
andorran
'european' is the definition.
(I know that Andorran is a type of european)
'lands boundlessly managed locking up gold' is the wordplay.
'lands boundlessly' becomes 'and' (I can't explain this - if you can you should give a lot more credence to this answer).
'managed' becomes 'ran' (I've seen this in another clue).
'locking up' means one lot of letters goes inside another (I've seen this in other clues).
'gold' becomes 'or' ('or' is the heraldic name for gold).
'and'+'ran'='andran'
'andran' going around 'or' is 'ANDORRAN'.
Can you help me to learn more?
(Other definitions for andorran that I've seen before include "Native to a principality in the Pyrenees" , "Resident of microstate" , "European" .)
