So a post office for each area is a drama? (4,5)
I believe the answer is:
soap opera
'a drama?' is the definition.
(thesaurus)
'so a post office for each area' is the wordplay.
'post office' becomes 'po'.
'for each' becomes 'per' (I've seen this before).
'area' becomes 'a' (maths abbreviation).
'so'+'a'+'po'+'per'+'a'='SOAP-OPERA'
'is' acts as a link.
(Other definitions for soap opera that I've seen before include "Regularly broadcast series" , "Serialised domestic melodrama on TV or radio" , "TV serial such as Coronation Street" , "addictive programme?" , "Television serial" .)
