Building in any rebellion (7)
I believe the answer is:
anarchy
'rebellion' is the definition.
(thesaurus)
'building in any' is the wordplay.
'building' becomes 'arch'.
'in' means one lot of letters goes inside another.
'arch' put inside 'any' is 'ANARCHY'.
(Other definitions for anarchy that I've seen before include "Absence of government" , "State of lawlessness and disorder" , "Lawlessness; chaos" , "Unrule" , "State of civil disorder" .)
