Complained article suppressed by second editor (6)
I believe the answer is:
moaned
'complained' is the definition.
(I've seen this in another clue)
'article suppressed by second editor' is the wordplay.
'article' becomes 'an' (English indefinite article).
'suppressed by' is a charade indicator (letters next to each other).
'second' becomes 'mo' (both are short periods of time).
'editor' becomes 'ed' (abbreviation).
'an' put after 'mo' is 'moan'.
'moan'+'ed'='MOANED'
(Other definitions for moaned that I've seen before include "A demon (anag.)" , "Made low mournful sound as of pain" , "Made low sound of pain - or grumbled" , "Complained" , "Made low sound of pain or distress" .)
