Religious ado, violent unfortunately (10)

I believe the answer is:

devotional

I'm a little stuck... Click here to teach me more about this clue!

'religious' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?

'ado violent unfortunately' is the wordplay.
'unfortunately' indicates an anagram (a bad or unfortunate spelling).
'ado'+'violent'='adoviolent'
'adoviolent' is an anagram of 'DEVOTIONAL'.

Can you help me to learn more?

(Other definitions for devotional that I've seen before include "Of worship" , "Short prayer service" .)

I've seen this clue in The Guardian.
