strontium

strontium

UK[ˈstrɒntiəm]US[ˈstrɑːnʃiəm]
n

A soft, silver-white or yellowish metallic chemical element (symbol Sr) that is highly reactive and used in some alloys and fireworks.

Etymology

The element's name originates from the Scottish village of Strontian, where the mineral strontianite was first discovered in 1790. The chemist Sir Humphry Davy isolated the metallic element in 1808 and named it 'strontium' after the mineral's locality. This follows the scientific convention of naming newly discovered elements after the geographical location of their source mineral. The name's journey from a Gaelic place name to a term on the periodic table exemplifies the modern practice of deriving technical vocabulary from proper nouns.

Analysis

The entire word "strontium" is a modern scientific coinage derived from a proper name. It is not productively segmented into smaller, meaningful morphemes in English.
