He gave Abel stick, we hear (4)
I believe the answer is:
cain
'he gave abel' is the definition.
The definition suggests a singular noun which matches the answer.
'stick we hear' is the wordplay.
'stick' becomes 'cane' (cane is a kind of stick).
'we hear' indicates a 'sounds like' (homophone) clue.
'cane' is a homophone of 'CAIN'.
Can you help me to learn more?
(Other definitions for cain that I've seen before include "The first known murderer" , "Slayer of Abel" , "First son" , "Abel's brother" , "Eve's firstborn" .)
