Disconcerted Punch journalist supporting article (7)
I believe the answer is:
abashed
'disconcerted' is the definition.
(abashing is a kind of disconcerting)
'punch journalist supporting article' is the wordplay.
'punch' becomes 'bash'.
'journalist' becomes 'ed' (short for editor).
'supporting' means one lot of letters go next to another (in a down clue, some letters go below others).
'article' becomes 'a' (the indefinite article in English).
'bash'+'ed'='bashed'
'bashed' put after 'a' is 'ABASHED'.
(Other definitions for abashed that I've seen before include "Caused to feel uneasy and self-conscious" , "turned red?" , "Disconcerted or ashamed" , "Stricken with shame" , "Shamefaced" .)
