means A record of people, groups, or things marked as untrustworthy or forbidden, used to deny them access, opportunity, or approval.

from First recorded in the 1600s, built simply from 'black' (long tied to the sinister, the forbidden, the disgraced) plus 'list' — an actual written roll of names. Early blacklists were literal documents kept by merchants, guilds, and governments to track debtors, troublemakers, or political enemies. The color coding wasn't arbitrary: 'black' had centuries of use meaning ominous or damned, paired against 'white' as pure or approved — a binary that shows up in other old pairs like blackball and whitelist. No single inventor, no single dramatic origin story — just a dark adjective doing exactly the job it sounds like it should.
