Present participle of bankrupt; the process of causing someone or an organization to become insolvent or unable to pay debts.
From 'bankrupt' as a verb (to make bankrupt) plus '-ing' suffix; the verb form emerged later than the noun, becoming common in the 16th-17th centuries.
The phrase 'bankrupting yourself' became a common warning because historically, one bad harvest, failed merchant voyage, or bad investment could literally destroy a family's entire wealth in days!
