Kind newspaper boss put in order (6)
I believe the answer is:
sorted
'put in order' is the definition.
(I've seen this in another clue)
'kind newspaper boss' is the wordplay.
'kind' becomes 'sort' (synonyms).
'newspaper boss' becomes 'ed' (short for editor).
'sort'+'ed'='SORTED'
(Other definitions for sorted that I've seen before include "Put into correct sequence" , "Job done!" , "Arranged into groups" , "organised" , "Classified - problem solved!" .)
