Neglected newspaper needs good editor (6)
I believe the answer is:
Here is my best explanation:
'neglected' is the definition.
'newspaper needs good editor' is the subsidiary indication.
'newspaper' becomes 'rag' (rag is a kind of newspaper).
'needs' means one lot of letters go next to another.
'good' becomes 'g' (abbreviation).
'editor' becomes 'ed'.
(Other definitions for ragged that I've seen before include "Made fun of; tattered", "Scruffy", "down at heel", "shabby", "Made or performed unevenly", "Clothes that are worn or torn", "Frayed or lacking smoothness", "taunted", "Old and torn, clothes say" and "made fun of".)
