Religious and evil too, unfortunately (10)
I believe the answer is:
devotional
'religious' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'and evil too unfortunately' is the wordplay.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'and'+'evil'+'too'='andeviltoo'
'andeviltoo' with letters rearranged gives 'DEVOTIONAL'.
Can you help me to learn more?
(Other definitions for devotional that I've seen before include "Of worship" , "Short prayer service" .)
