What does ligneous mean?
Ligneous is a formal adjective meaning woody or woodlike. It is used especially in botanical and biological writing to describe plant tissue that has a hard, fibrous structure, or any material whose composition resembles wood. The word is more technical than the everyday term woody, but it conveys the same basic idea with greater precision. A specialist might describe a plant stem as having ligneous fibers, or a pathologist might identify ligneous tissue in a specimen. In general contexts, ligneous can also refer metaphorically to something that is stiff, solid, or durable, though such figurative uses are less common. The word is useful for readers of scientific and historical texts because it identifies the distinctive physical character of wood and the process by which plant tissues become woodlike.
