sicario

Latin sica was a short curved knife associated with assassins rather than soldiers. Men who carried the sica were sicarii, dagger-men. In first-century Judea, a group of Jewish zealots adopted the name deliberately: they concealed their blades beneath festival cloaks, moved through Jerusalem crowds, killed Roman collaborators at close range, and vanished before anyone understood what had happened. The historian Josephus documented them in The Jewish War around 75 CE.

Latin sicarius passed into Spanish legal language as a technical term for a paid killer, distinct from a soldier acting under orders or a murderer in passion. Spanish legal codes from the 16th century onward used sicario for contract killing. The word carried the ancient specificity of the hidden blade, killing arranged in advance, for hire, in cold calculation.

In 20th-century Latin America, particularly in Colombia and Mexico, sicario became the everyday word for a cartel hitman. The Medellin cartel in the 1980s employed thousands of young men this way. Fernando Vallejo's 1994 novel La Virgen de los Sicarios and Jorge Franco's 1999 novel Rosario Tijeras brought the word into literary Spanish with a clarity that journalism alone could not provide.

English borrowed sicario without translation through crime reporting and film. Denis Villeneuve's 2015 film Sicario opened with a title card explaining the word, evidence that English speakers needed the definition but the Spanish term was kept because hitman lacked the cultural and geographic specificity. The word now appears in English-language reporting across Latin America without italics or translation.
