Relating to or characteristic of the element germanium or containing germanium.
From Germanic: from Latin 'Germanicus' (Germanic) + -ous. This chemical term was coined when the element germanium was discovered and chemists needed adjectives to describe its properties.
Germanium was actually predicted to exist by the Russian scientist Mendeleev using his periodic table before anyone found it—so 'germanious' describes something that matched a mathematical prediction!
