Tries to interrupt Spanish team's practice (9)
I believe the answer is:
rehearsal
'practice' is the definition.
(rehearsal is a kind of practice)
'tries to interrupt spanish team's' is the wordplay.
'tries' becomes 'hears' ('hear' can be a synonym of 'try').
'to interrupt' indicates putting letters inside.
'spanish team's' becomes 'real' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hears' inserted inside 'real' is 'REHEARSAL'.
Can you help me to learn more?
(Other definitions for rehearsal that I've seen before include "Dummy run" , "show trial" , "Practice in theatre etc" , "preparation in house?" , "Drill" .)
