Etymology
The word 'lignite' is a modern scientific term coined in the early 19th century to describe a specific type of coal. It is formed directly from the Latin root lignum, meaning "wood", reflecting the material's origin as compacted and chemically altered plant matter, primarily wood from ancient forests. The suffix -ite, borrowed from Greek via Latin and French, is commonly used in mineralogy to denote natural rocks or fossils. Thus, the term's literal construction as "wood-rock" perfectly captures its essence as a fossil fuel derived from woody peat that has undergone only a moderate degree of coalification.
Analysis

- lign: From Latin lignum, meaning "wood".
- ite: A suffix from Greek -itēs, used in geology to denote minerals, rocks, or fossils.
Examples
The power plant was designed to burn lignite, a plentiful but low-grade fuel in the region.
Geologists identified the layer as lignite due to its brown color and woody texture.
Compared to anthracite, lignite has a lower carbon content and higher moisture level.
