Victoria area rave in church building (8)
I believe the answer is:
vicarage
'church building' is the definition.
'vicarage' can be an answer for 'building' (thesaurus). I am not certain of the 'church' bit.
'victoria area rave' is the wordplay.
'victoria' becomes 'vic' (nickname).
'area' becomes 'a' (maths abbreviation).
'rave' becomes 'rage' (both can mean to behave angrily).
'vic'+'a'+'rage'='VICARAGE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for vicarage that I've seen before include "Church dwelling" , "Rectory" , "Church accommodation" , "6's residence" , "house near church?" .)
