Unusually harder quest capturing a camp (12)
I believe the answer is:
headquarters
'camp' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'unusually harder quest capturing a' is the wordplay.
'unusually' is an anagram indicator.
'capturing' indicates putting letters inside.
'harder'+'quest'='harderquest'
'harderquest' is an anagram of 'headqurters'.
'headqurters' enclosing 'a' is 'HEADQUARTERS'.
Can you help me to learn more?
(Other definitions for headquarters that I've seen before include "Military command post" , "Command centre" , "Centre of operations" , "Base" , "HQ" .)
