A lark fluttering around the compound (5)
I believe the answer is:
kraal
'the compound' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'a lark fluttering around' is the wordplay.
'fluttering' indicates an anagram.
'around' means one lot of letters goes inside another.
'lark' is an anagram of 'kral'.
'a' put within 'kral' is 'KRAAL'.
Can you help me to learn more?
(Other definitions for kraal that I've seen before include "South African village" , "African hutted village" , "Traditional African village" , "Corral" , "Pen" .)
