Dive or rush with some speed around the court! (5)
I believe the answer is:
swoop
'dive' is the definition.
(I've seen this in another clue)
'rush with some speed around the court' is the wordplay.
'rush with some speed' becomes 'sp' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'around' indicates putting letters inside.
'the court' becomes 'woo' (both can mean to romance someone).
'sp' placed around 'woo' is 'SWOOP'.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for swoop that I've seen before include "Dive downwards" , "Predator's dive" , "Rush suddenly" , "Police raid" , "Descend suddenly (on)" .)
