Throw ball at British bird (4)
I believe the answer is:
bowl
'throw ball' is the definition.
'bowl' can be an answer for 'ball' (bowl is a kind of ball). I am not certain of the 'throw' bit.
'at british bird' is the wordplay.
'at' means one lot of letters go next to another.
'british' becomes 'b' (abbreviation e.g. in BBC).
'bird' becomes 'owl' (owl is a kind of bird).
'b'+'owl' is 'BOWL'.
Can you help me to learn more?
(Other definitions for bowl that I've seen before include "Deep dish or basin" , "Soup dish - roll a ball" , "Round dish, basin" , "Throw the ball" , "Play with tenpins" .)
