Reconstruction:Proto-Slavic/tъrgъ

Of unclear origin. According to some, connected with the word *toržìti (“to seek, look for”), cf Serbo-Croatian trážiti (“to trace”) from Proto-Slavic *tragъ, from Proto-Indo-European *tregʰ-, a variation of *dʰregʰ- (“to pull, draw, drag”). Cognates include Latin trahō and Old Irish traig (“foot”). For a semantic parallel compare Hungarian keres (“to seek, look for”) : kereskedelem (“trade, commerce”).

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 Balkan 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.

1. merchandise, commodity, wares
