Passionate - that could be us after a second run out (7)
I believe the answer is:
amorous
'passionate' is the definition.
('amorous' can be similar in meaning to 'passionate')
'us after a second run out' is the wordplay.
'after' means one lot of letters go next to another.
'second' becomes 'mo' (both are short periods of time).
'run out' becomes 'ro' (cricket abbreviation).
'a'+'mo'+'ro'='amoro'
'us' put after 'amoro' is 'AMOROUS'.
'that could be' acts as a link.
(Other definitions for amorous that I've seen before include "Expressing love" , "Fond" , "characterising a romantic sort" , "Showing or feeling loving feeling" , "Loving, passionate" .)
