Remembers spiritual lessons with short prayers (10)
I believe the answer is:
recollects
'remembers' is the definition.
('recollect' can be a synonym of 'remember')
'spiritual lessons with short prayers' is the wordplay.
'spiritual lessons' becomes 're' (Religious Education. I am not sure about the 'spiritual' bit.).
'with' is a charade indicator (letters next to each other).
'short prayers' becomes 'collects' (a 'collect' is a type of short prayer; 'short' indicates a short form).
're'+'collects'='RECOLLECTS'
Can you help me to learn more?
(Another definition for recollects that I've seen is " Remembers".)
