dead cert

Absolutely certain outcome

A dead cert is something absolutely certain to happen or succeed—a sure thing.

The phrase comes from horse racing, where a cert (certainty) is a horse considered guaranteed to win; dead intensifies it to mean utterly beyond doubt.

Primarily British: He's a dead cert for the promotion.

Americans more often say sure thing or lock.
