What could be chained outside a foreign estate (8)
I believe the answer is:
hacienda
'foreign estate' is the definition.
'hacienda' can be an answer for 'estate' (hacienda is a kind of estate). I am not sure about the 'foreign' bit.
'what could be chained outside a' is the wordplay.
'what could be' indicates an anagram.
'outside' means one lot of letters goes inside another (some letters go outside others).
'chained' with letters rearranged gives 'hcienda'.
'hcienda' enclosing 'a' is 'HACIENDA'.
Can you help me to learn more?
(Other definitions for hacienda that I've seen before include "Spanish house/estate" , "home overseas" , "estate abroad" , "country estate" , "Ranch with mansion" .)
