The municipality lies in the southern Hunsrück in the Unnertal (Unnerbach valley) in the west of Rhineland-Palatinate near the state boundary with the Saarland.

It may be, though, that the first half of this hyphenated name comes from the archaic word Forrn (in modern German, Forelle – “trout”).

The municipality's arms might in English heraldic language be described thus: Argent a bar and in base a vergette couped at the bar sable, issuant from the bar a demilion azure armed and langued gules, in dexter base a pine twig slipped bendwise proper and in sinister base a lime leaf slipped vert.

The lion is a reference to the village's former allegiance to the Counts of Veldenz in the Middle Ages.
