'risk torment or halt marriage arrangements' is the definition.
I can't tell whether this defines the answer.

'risk torment or halt' is the wordplay.
'risk' becomes 'bet' (I've seen this in another clue).
'torment' indicates an anagram (I've seen 'tormented' mean this).
'or'+'halt'='orhalt'
'orhalt' anagrammed gives 'rothal'.
'bet'+'rothal'='BETROTHAL'

Can you help me to learn more?
