Etymology

It is from Latin latrō2 (“mercenary; robber”) + -cinor.[1][2] The OLD explains it as made from latrōcinium (“military service for pay; brigandage”) in the same way.[3] The origin of that noun for “mercenary” is disputed: it is often compared with Ancient Greek λάτρις (látris, “hired servant”) and traced to an Indo-European root, but Beekes takes it as a borrowing from an unattested *λάτρων (*látrōn).[1]

Earliest recorded meaning

The TLL first records it in Plautus,[2] in the old sense of serving as a hired soldier: in the Miles Gloriosus a soldier's slave is asked whether he thinks he may do as he likes because he and his fellows serve for pay.[3][2]

Semantic evolution

Its early sense, “to serve as a mercenary”, belongs to Plautus, who also has a man going off to serve in Asia or Cilicia and another who served King Demetrius for ten years;[3][4] in the Poenulus he uses it jokingly of things that “rob” a man because they want ready cash.[2] Lewis & Short call this sense ante-classical.[4]

From Cicero on it means “to practise brigandage”: Catiline would rather be killed as a brigand than live as an exile, and the Cretans and Aetolians, Cicero says, think robbery honourable;[3][4] he also uses it of piracy, setting seafaring peoples who sailed for trade beside those who sailed to plunder.[4][5] Celsus applies it to a doctor who dissects a body, and Pliny the Elder to the stingray, which lies in ambush and strikes passing fish with its spine.[3][4][6]

It is also used transitively, of harrying a stretch of land or sea: Seneca the Elder speaks of pirates who plunder lands and seas alike, and Florus has it of a gulf.[3][7] Eutropius construes it with a dative, of capturing Roman ships.[6] An active form is found in the Historia Augusta, and Augustine has the adverb latrōcinanter, “like a robber”.[6][4]
