Get the game started (5)
I believe the answer is:
flush
'get' is the definition.
The answer and definition can be both related to bodily activities as well as being verbs in their base form.
Maybe you can see an association between them that I can't see?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for flush that I've seen before include "Poker hand of same suit" , "Rich" , "Look ashamed < , maybe even promising hand" , "Rush of blood" , "with a load of cash" .)
