Quietly direct to pray (5)
I believe the answer is:
'to pray' is the definition.
(I've seen this in another clue)
'quietly direct' is the wordplay.
'quietly' becomes 'p' (musical symbol).
'direct' becomes 'lead' (direct can mean to lead someone somewhere).
(Other definitions for plead that I've seen before include "Appeal humbly (to)" , "State whether one is guilty or not" , "Beg, implore" , "Appeal earnestly" , "Request" .)
