Willing to finish in debt (8)
I believe the answer is:
endowing
'willing' is the definition.
The definition and answer can be both to do with ownership as well as being present participle verbs.
Perhaps there's a link between them I don't understand?
'finish in debt' is the wordplay.
'finish' becomes 'end' (synonyms).
'in debt' becomes 'owing' (I've seen this before).
'end'+'owing'='ENDOWING'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for endowing that I've seen before include "Presenting" , "Making donations" .)
