Journalist covering peculiar tale is jubilant (6)
I believe the answer is:
elated
'jubilant' is the definition.
('elated' can be a synonym of 'jubilant')
'journalist covering peculiar tale' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'covering' indicates putting letters inside.
'peculiar' indicates an anagram (I've seen this in other clues).
'tale' is an anagram of 'late'.
'ed' enclosing 'late' is 'ELATED'.
'is' acts as a link.
(Other definitions for elated that I've seen before include "Euphoric" , "Intensely delighted and proud" , "In very high spirits, really chuffed" , "Overjoyed, in high spirits" , "Very pleased, quite high" .)
