Stop offering no initial comfort (4)
I believe the answer is:
ease
'comfort' is the definition.
(I know that ease is a more specific form of the action comfort)
'stop offering no initial' is the wordplay.
'stop' becomes 'cease' (synonyms).
'offering no initial' means to remove the first letter.
'cease' with its first letter taken away is 'EASE'.
(Other definitions for ease that I've seen before include "Absence of effort" , "Freedom from pain or anxiety" , "Allay" , "composure" , "No trouble" .)
