Silver
Silver is a chemical element with symbol Ag (from the Latin "", derived from the Proto-Indo-European "h₂erǵ": "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
Arenrath
The escutcheon’s silver parting (described in the German blazon as a "Stufenbalken", and apparently having no equivalent in English heraldic language) and the begging bowl are said to be references to the local church’s patron saint, Alexius, who is represented in legend as a beggar under a staircase. The wheat ears stand for agriculture and the field tincture vert (green) is a reference to the municipality’s name, Arenrath, which itself refers to “Arend’s clearing”. Green stands for woods and fields while the gules-argent (red-silver) combination is a reference to the village’s former allegiance to the Electorate of Trier.
