Laity confused about new kind of prayer (6)
I believe the answer is:
litany
'kind of prayer' is the definition.
'laity confused about new' is the wordplay.
'confused' is an anagram indicator.
'about' means one lot of letters goes inside another.
'new' becomes 'n'.
'laity' is an anagram of 'litay'.
'litay' enclosing 'n' is 'LITANY'.
(Other definitions for litany that I've seen before include "Lay tin down on the prayer" , "Prayer of supplication" , "Repeated prayers" , "A series of supplications to God" , "long address" .)
