Worried chaps collared by wrong sort of journalist (9)
I believe the answer is:
tormented
'worried' is the definition.
(I've seen this before)
'chaps collared by wrong sort of journalist' is the wordplay.
'chaps' becomes 'men' (chap means a man).
'collared by' indicates putting letters inside (I've seen this in other clues).
'wrong sort of' becomes 'tort' (I can't justify this - if you can you should believe this answer much more).
'journalist' becomes 'ed' (short for editor).
'men' inserted within 'tort' is 'torment'.
'torment'+'ed'='TORMENTED'
Can you help me to learn more?
(Other definitions for tormented that I've seen before include "Made to suffer" , "Distressed" , "Harassed" , "Worried" , "Suffering severely" .)
