Accident with 50 in church area (7)
I believe the answer is:
chancel
'church area' is the definition.
'chancel' can be an answer for 'church' (I've seen this before). I'm unsure of the 'area' bit.
'accident with 50' is the wordplay.
'accident' becomes 'chance' (I've seen this in other clues).
'with' is a charade indicator (letters next to each other).
'50' becomes 'L' (roman numeral).
'chance'+'l'='CHANCEL'
'in' is the link.
Can you help me to learn more?
(Other definitions for chancel that I've seen before include "what's behind the screen" , "space for choir" , "church, partly" , "Clergy's area of the church" , "Area around the altar of a church" .)
