Jubilant journalist following story in review (6)
I believe the answer is:
elated
'jubilant' is the definition.
('elated' can be a synonym of 'jubilant')
'journalist following story in review' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'following' says to put letters next to each other.
'story' becomes 'tale' ('tale' can be a synonym of 'story').
'in review' is a reversal indicator.
'tale' written backwards gives 'elat'.
'ed' after 'elat' is 'ELATED'.
(Other definitions for elated that I've seen before include "Cock-a-hoop" , "Over the moon" , "Very pleased, quite high" , "Greatly delighted and proud" , "In high spirits, very pleased" .)
