Defeat for a bet? (4)
I believe the answer is:
beat
'defeat' is the definition.
(synonyms)
'a bet?' is the wordplay.
'a bet' anagrams to 'BEAT'.
However, I am unsure how this is indicated.
'for' is the link.
Can you help me to learn more?
(Other definitions for beat that I've seen before include "Tan" , "Surpass (a score)" , "Baffle - all in" , "tired" , "course for law enforcement officers" .)
