Switch for display, in a way, in church (6)
I believe the answer is:
change
'switch for display' is the definition.
'change' can be an answer for 'switch' ('change' can be a synonym of 'switch'). I'm unsure of the 'for display' bit.
'a way in church' is the wordplay.
'a way' becomes 'hang' (hang is a kind of way**).
'in' is an insertion indicator.
'church' becomes 'ce' (abbreviation for Church of England).
'hang' going into 'ce' is 'CHANGE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for change that I've seen before include "Alter for small coins" , "Best not to do it in 12" , "Innovation" , "Loose money in pocket" , "Alter, convert" .)
