Valuing unexpected gift, he stops making money from scrap? (13)
I believe the answer is:
prizefighting
'making money from scrap?' is the definition.
I can't judge whether this defines the answer.
'valuing unexpected gift he stops' is the wordplay.
'valuing' becomes 'prizing' ('prize' can be a synonym of 'value').
'unexpected' indicates an anagram.
'stops' means one lot of letters goes inside another (to stop can mean to block a gap).
'gift'+'he'='gifthe'
'gifthe' is an anagram of 'efight'.
'prizing' going around 'efight' is 'PRIZEFIGHTING'.
Can you help me to learn more?
(Another definition for prizefighting that I've seen is " Sport".)
