Trerus

• Tolerus

Borrowed from Ancient Greek Τρῆρος (Trêros). The stem *tol in its alternative form can be compared with the city Tolentinum in Picenum, and possibly Toletum in Hispania and modern French Toulouse in France. Or, possible Proto-Indo-European origins include *tel- (“to be still”) (Lithuanian tyla (“silence”)), *telh₂- (“flat ground, bottom”) or *telh₂- (“to transport, carry”).

• (Classical) IPA^(key): /ˈtreː.rus/, [ˈt̪reːrʊs̠]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈtre.rus/, [ˈt̪rɛːrus]
