Word OriginMiddle English: from Old French brochier, based on Latin brocchus, broccus ‘projecting’. The earliest recorded sense was ‘prick with spurs’, generally ‘pierce’, which gave rise (late Middle English) to broach1 (sense 2). broach1 (sense 1), a figurative use of this, dates from the late 16th century.
