I do insane pranks for neighbour (9)
I believe the answer is:
indonesia
'neighbour' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'i do insane pranks' is the wordplay.
'i do insane' anagrams to 'INDONESIA'.
But, I am not sure how the anagram is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for indonesia that I've seen before include "Muslim republic" , "Asian country, capital Jakarta" , "part of Asia" , "State" , "An ionised country of South East Asia" .)
