Relaxed, like journalist after magazine's closure (5)
I believe the answer is:
eased
'relaxed' is the definition.
(I've seen this in another clue)
'like journalist after magazine's closure' is the wordplay.
'like' becomes 'as'.
'journalist' becomes 'ed' (short for editor).
'after' is a charade indicator (letters next to each other).
'closure' suggests the final letters (the letter which closes the word).
The final letter of 'magazine' is 'e'.
'as'+'ed'='ased'
'ased' put after 'e' is 'EASED'.
(Other definitions for eased that I've seen before include "Given relief" , "Allievated" , "Allayed" , "Helped" , "Calmed" .)
