Club player in action endlessly before birdie (6)
I believe the answer is:
deejay
'club player' is the definition.
'deejay' can be an answer for 'player' (I have seen 'Player of records ' mean 'deejay' so perhaps 'player' could also mean 'deejay'). I am not certain of the 'club' bit.
'action endlessly before birdie' is the wordplay.
'action' becomes 'deed' (deed is a kind of action).
'endlessly' means to remove the last letter.
'before' says to put letters next to each other.
'birdie' becomes 'jay' ().
'deed' with its last letter taken away is 'dee'.
'dee'+'jay'='DEEJAY'
'in' is the link.
Can you help me to learn more?
(Other definitions for deejay that I've seen before include "Radio disc man" , "Radio presenter" , "Record spinner" , "Informal disc jockey" , "provider of music" .)
