Forms

trochus m (genitive trochī); second declension[1]

Etymology

It is borrowed from Ancient Greek τροχός (trokhós, “wheel”),[2][1][3] from τρέχω (trékhō, “to run”).[4] Köbler traces the Greek to Proto-Indo-European *dʰregʰ- (“to run”).[5]

Earliest recorded meaning

Köbler records it from Laevius onwards.[5] Köbler dates Laevius to the 2nd/1st century BC.[5]

Semantic evolution

It was a metal hoop hung with small rings that jingled, bowled by boys as a game or exercise.[2][6] Horace speaks of a youth more skilled at playing with the Greek hoop or with forbidden dice, and Propertius, Ovid and Martial mention it too.[2][3] Pliny the Elder uses it of an unidentified fish.[2]

British medieval writers used it of a hoop and of a top.[7] Etymonline says English truck “small wheel”, recorded in the 1610s, is probably from this word.[4]
