Tell story backwards during scripture lesson (6)
I believe the answer is:
relate
'tell' is the definition.
(as in to tell or relate a story)
'story backwards during scripture lesson' is the wordplay.
'story' becomes 'tale' (synonyms).
'backwards' is a reversal indicator.
'during' is an insertion indicator.
'scripture lesson' becomes 'RE' (abbreviation for Religious Education).
'tale' written backwards gives 'elat'.
'elat' placed into 're' is 'RELATE'.
(Other definitions for relate that I've seen before include "Describe an event" , "Narrate in Tralee" , "Marriage Guidance - report" , "Tell (a story)" , "Make a logical or causal connection" .)
