Male rugby player initially doubled in value? (4)
I believe the answer is:
cock
'male' is the definition.
(male chicken)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cock that I've seen before include "Male lobster; valve" , "Make gun ready" , "early rouser" , "Prepare to shoot" , "bull to > raise for shooting" .)
