Embarrassed journalist seen after a party (7)
I believe the answer is:
abashed
'embarrassed' is the definition.
(synonyms)
'journalist seen after a party' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'seen after' is a charade indicator (letters next to each other).
'party' becomes 'bash' (term for a party or celebration).
'a'+'bash'='abash'
'ed' put after 'abash' is 'ABASHED'.
(Other definitions for abashed that I've seen before include "Embarrassed or ashamed" , "turned red?" , "Embarrassed or disconcerted" , "Disconcerted or ashamed" , "floored" .)
