## Origin

The idiom emerged in 1854 as New York City criminal slang. It functions as a compound of dead, used in the sense of completely or utterly, and the phrase to rights, meaning properly. While the criminals of the mid-19th century have largely vacated the premises, their terminology for being caught in an indisputable state of guilt entered general use shortly thereafter.
