One accepting bet — selfish sort? (5)
I believe the answer is:
taker
'selfish sort?' is the definition.
(I've seen this in another clue)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for taker that I've seen before include "Person accepting an offer" , "one's prepared to bet" , "He accepts" , "Person seizing something" , "(Challenge) acceptor" .)
