Prayerful, reflective verse editor dismissed (6)
I believe the answer is:
devout
'prayerful' is the definition.
(thesaurus)
'reflective verse editor dismissed' is the wordplay.
'reflective' says the letters should be written backwards.
'verse' becomes 'v'.
'editor' becomes 'ed' (abbreviation).
'dismissed' becomes 'out' (I've seen this before).
'v'+'ed'='ved'
'ved' reversed gives 'dev'.
'dev'+'out'='DEVOUT'
(Other definitions for devout that I've seen before include "Pious, given to prayer" , "Deeply religious" , "Religiously committed" , "Reverent" , "God-fearing" .)
