Etymology: Latin "aurum" meant gold, and its English descendant is "or", which entered the language through Old French. Both words come from the same Latin source, so English ended up with two forms: "aurum" as a learned, scientific borrowing used directly in chemistry, and "or" as an everyday word passed down through French. That pairing makes "or" a doublet of "aurum", the term for two words that split from one root and took different routes into the language. The chemical symbol Au on the periodic table comes from the same Latin stem. Scientists writing in Latin for centuries used "aurum" as the formal name, which is why the symbol reflects the Latin word rather than the English one.

Synonyms: gold, Au, precious metal
