beryllium
UK[bəˈrɪliəm]US[bəˈrɪliəm]
n
A hard, light, silver-white metallic chemical element, used in making strong, light alloys.
Etymology
The element's name originates from the mineral beryl, in which it was first discovered. 'Beryl' itself comes from Latin 'beryllus' and Greek 'bēryllos', referring to a precious blue-green stone. The suffix '-ium' is a standard Latinate ending used in chemistry to denote metallic elements, paralleling names like 'lithium' and 'sodium'. Thus, 'beryllium' literally means "the metal from beryl," connecting its discovery source to its modern identity on the periodic table.
Analysis
The word is a modern scientific formation derived directly from the name of the mineral 'beryl'. It functions as a simplex noun naming a chemical element.
Examples
Beryllium is alloyed with copper to make strong, non-sparking tools.
The window of an X-ray tube is often made of thin beryllium foil.
Due to its toxicity, handling beryllium requires strict safety precautions.
