A rare or invented term possibly referring to the act or condition of becoming bankrupt; a non-standard form (appears to be obsolete or fabricated).
Potentially from 'bankrupt' plus '-ure' suffix (as in 'closure,' 'fracture'), though this formation is not standard in English and is either extremely archaic or not historically attested.
Words like 'bankrupture' show how easy it would be to create new English words following standard rules, but they don't exist because English speakers collectively rejected them in favor of 'bankruptcy'!
