Excited about an extraordinarily late edition? (6)
I believe the answer is:
elated
'excited' is the definition.
(elating is a kind of exciting)
'an extraordinarily late edition?' is the wordplay.
'an extraordinarily' indicates an anagram (I've seen this in other clues).
'edition?' becomes 'ed'.
'late' is an anagram of 'elat'.
'elat'+'ed'='ELATED'
'about' acts as a link.
(Other definitions for elated that I've seen before include "Jubilant, overjoyed" , "Very pleased, quite high" , "Filled with joy and pride" , "Joyful, uplifted" , "Full of high-spirited delight" .)
