Splitting chocolate bar to be eaten by hazard (7)
I believe the answer is:
betwixt
'splitting chocolate' is the definition.
I can't judge whether this definition defines the answer.
'bar to be eaten by hazard' is the wordplay.
'bar' becomes 'twix' (chocolate bar).
'to be eaten by' means one lot of letters goes inside another (inserted letters get eaten).
'hazard' becomes 'bet' (both can mean to gamble or risk).
'twix' put inside 'bet' is 'BETWIXT'.
Can you help me to learn more?
(Other definitions for betwixt that I've seen before include "In the middle of" , "Old word for between" , "Between (arch.)" .)
