Ever reflective, admits lie to comfort and reassure (7)
I believe the answer is:
relieve
'reassure' is the definition.
(thesaurus)
'ever reflective admits lie' is the wordplay.
'reflective' shows that the letters should be reversed in order.
'admits' is an insertion indicator (to admit is to allow in).
'ever' back-to-front is 'reve'.
'reve' placed around 'lie' is 'RELIEVE'.
'to comfort and' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for relieve that I've seen before include "help" , "Assuage - take over duty from" , "Ease pain or burden" , "Comfort" , "Lighten a burden or raise a seige" .)
