The Latin place-name Tergeste (whence Italian Trieste), first attested around 100 BC (by the Greek geographer Artemidorus of Ephesus), possibly from Venetic, but with the typically Illyrian suffix -est-, has often been derived from a *terg- which is speculated to mean "market" or "marketplace" and to be cognate with the Slavic lexeme.
