betrothed

'intended' is the definition.
(I've seen this before)

'out other debt' is the wordplay.
'out' is an anagram indicator.
'other'+'debt'='otherdebt'
'otherdebt' anagrammed gives 'BETROTHED'.

'to wipe' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for betrothed that I've seen before include "Engaged - fiance" , "intended" , "Spoken for" , "committed somehow" , "Promised in marriage" .)
