Charm with which a religious dissertation is read out (7)
I believe the answer is:
attract
'charm' is the definition.
(thesaurus)
'a religious dissertation is read out' is the wordplay.
I cannot really understand how this works, but
'a' is present in the answer.
'dissertation' could be 'tract' (I've seen this in another clue) and 'tract' is found in the answer.
A single letter 't' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'with which' is the link.
(Other definitions for attract that I've seen before include "Exert a pull upon" , "Entice" , "Draw, pull" , "Act as a magnet" , "Exercise a magnetic influence" .)
