Butch old lady sits on church official's head (5)
I believe the answer is:
macho
'butch' is the definition.
(synonyms)
'old lady sits on church official's head' is the wordplay.
'old lady' becomes 'ma' (both can mean mother).
'sits on' says to put letters next to each other.
'church' becomes 'ch' (abbreviation on maps etc).
'head' suggests taking the first letters.
The first letter of 'officials' is 'o'.
'ma'+'ch'+'o'='MACHO'
(Other definitions for macho that I've seen before include "Jock" , "Laddish" , "Blokeish" , "Butch" , "Excessively male" .)
