Harp is drunk in father's district (6)
I believe the answer is:
parish
'father's district' is the definition.
'parish' can be an answer for 'district' (parish is a kind of district). I'm not certain of the 'father's' bit.
'harp is drunk' is the wordplay.
'drunk' indicates an anagram.
'harp'+'is'='harpis'
'harpis' anagrammed gives 'PARISH'.
'in' is the link.
Can you help me to learn more?
(Other definitions for parish that I've seen before include "Diocesan subdivision" , "Kind of 2 down - has rip (anag)" , "District with own church and clergyman" , "Area within diocese with own church" , "Local church community" .)
