Learner calm after religious education is free (7)
I believe the answer is:
release
'is free' is the definition.
(I've seen this before)
'learner calm after religious education' is the wordplay.
'learner' becomes 'l'.
'calm' becomes 'ease' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'religious education' becomes 're'.
'l'+'ease'='lease'
'lease' after 're' is 'RELEASE'.
(Other definitions for release that I've seen before include "Free - delivery" , "Authorise publication" , "New film" , "Free from confinement" , "put out" .)
