Swear allegiance at the front, church getting cross out (6)
I believe the answer is:
efface
'cross out' is the definition.
(thesaurus)
'swear allegiance at the front church' is the wordplay.
'swear' becomes 'eff' (I can't justify this - if you can you should give a lot more credence to this answer).
'at the front' suggests taking the first letters.
'church' becomes 'CE' (abbreviation for Church of England).
The first letter of 'allegiance' is 'a'.
'eff'+'a'+'ce'='EFFACE'
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for efface that I've seen before include "Delete, wipe out" , "The selling of goods in large quantities" , "Erase a mark from a surface" , "Obliterate by rubbing out" , "Rub out entirely, obliterate" .)
