Forms

chiliarca m (plural chiliarchi)[1] Variants are chiliarco and Old Italian ciliarca, with the plurals ciliarce and ciliarche.[2][3][4][5]

Etymology

It is a learned word: it is borrowed from Latin chiliarchus and Latin chiliarchēs, from Ancient Greek χιλίαρχος (khilíarkhos) and χιλιάρχης (khiliárkhēs).[2][3][6][5][1] The Greek words are compounds of χίλιοι (khílioi, “thousand”) and the stem of ἄρχω (árkhō, “I command”).[2][3][6][7]

GRADIT compares Old Persian hazārapati-, “commander of a thousand”, and Wiktionary treats the Greek title as a calque of a reconstructed Old Persian *hazahrapatiš.[6][1] Isidore already explained the Latin word as a Greek name for the officers the Latins called millenarii.[5]

Earliest recorded meaning

The oldest Italian record is the Old Sienese Fatti di Cesare of the late 13th century, in the form ciliarce: “Ciliarce erano conestabili di mille”, chiliarchs were commanders of a thousand, said of the Roman army.[4][5]

Semantic evolution

Fazio degli Uberti's Dittamondo lists chiliarche with centurions, masters of horse and decurions among the officers of Rome.[5][8] Tommaseo glossed the word as a colonel, a leader of a thousand men.[8]

In modern Italian it is a historical term for a commander of a thousand soldiers among the ancient Greeks, and for the officer in Persia who led the thousand noble horsemen of the Great King's guard.[2][6][3]
