Get thrilled when English story turns up (5)
I believe the answer is:
elate
'get thrilled' is the definition.
(to elate someone is to thrill them)
'english story turns up' is the wordplay.
'english' becomes 'e' (abbreviation).
'story' becomes 'tale' (synonyms).
'turns up' shows that the letters should be reversed in order.
'e'+'tale'='etale'
'etale' back-to-front is 'ELATE'.
'when' is the link.
(Other definitions for elate that I've seen before include "cheer" , "Inspirit, make exultant" , "Fill with joy" , "Bring joy" , "Overjoy" .)
