The word lignite comes from the Latin word lignum meaning wood. Their origin is mostly from plants rich in resin, so they are high in volatile matter. Freshly mined, lignite is tough, although not hard, and it requires a heavy blow with a hammer to break the large lumps. But on exposure to air, it loses moisture rapidly and disintegrates.

Lignite is the least calorific of all categories of coal (anthracite, bituminous, subbituminous, brown coal/lignite): this is due to its high moisture and volatile content and to its low carbon content. This means that lignite-fired plants are designed to burn specifically lignite and that it is expensive to turn them into coal-fired plants.
