In church, is it partly collapsed? (4)
I believe the answer is:
apse
'in church' is the definition.
(I've seen this before)
'it partly collapsed?' is the wordplay.
'APSE' is hidden in amongst the letters.
But, I am uncertain how this is indicated.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for apse that I've seen before include "Church area" , "Large recess in church" , "Projection to the east end of a church" , "Rounded end of building" , "Semicircular end of a church, behind the altar" .)
