What does bankroll mean?
A bankroll is a person's stock of readily available money, a term that originated in the literal image of paper currency rolled into a bundle for carrying. Today the noun is used both generally — anyone's pool of funds — and particularly in gambling, where a poker player's bankroll is the dedicated sum they can afford to wager, and managing it prudently is treated as a core skill. The verb form is equally important: to bankroll someone or something is to finance it, usually with one's own wealth, as when a tycoon bankrolls a political campaign, a film, or a fledgling company. The word carries connotations of substantial resources and often of risk-taking, since a bankroll is money put on the line rather than safely invested. Journalists frequently use 'bankroll' when describing deep-pocketed backers, making it a staple term in coverage of business, sports, politics, and entertainment.
A person's supply of money available for spending or wagering; originally a roll of banknotes.
"She dipped into her bankroll to cover the trip."
Especially common in gambling contexts.
To finance or underwrite a person, project, or enterprise with one's own money.
"Two local businessmen bankrolled the new stadium."
Rarely pluralized except when referring to multiple people's supplies of funds.
"Both players arrived with hefty bankrolls."
The word comes straight from gamblers who literally rolled their cash into bundles — and in poker, managing your 'bankroll' is considered a discipline of its own.

Where does bankroll come from?
Bankroll derives from 'bank', which entered English through Italian 'banca' meaning a moneylender's bench or counter, combined with 'roll', reflecting the practice of rolling banknotes into a cylinder for convenient carrying. It emerged in American English in the nineteenth century, initially describing a gambler's or traveler's roll of bills. Over time the sense broadened from a physical roll of cash to any reserve of money, and by the twentieth century the verb 'to bankroll' had developed to mean financing an undertaking, extending the gambling association into general commercial and journalistic use.
