Chaos having refurbished ranch within a year (7)
I believe the answer is:
anarchy
'chaos' is the definition.
(thesaurus)
'refurbished ranch within a year' is the wordplay.
'refurbished' indicates an anagram.
'within' means one lot of letters goes inside another.
'year' becomes 'y'.
'ranch' with letters rearranged gives 'narch'.
'a'+'y'='ay'
'narch' placed within 'ay' is 'ANARCHY'.
'having' is the link.
(Other definitions for anarchy that I've seen before include "Society without government or law, chaos" , "Complete absence of law" , "General disorder" , "Collapse of order, rule" , "State of lawlessness and disorder" .)
