Definition
Noun: A pine knot is a hard, dense, resinous section of wood found at the point where a branch grows from the trunk of a pine tree. Due to its high resin content, it burns very well and was historically valued as a source of fuel, especially for starting fires or providing long-lasting, hot embers.
Usage
A pine knot is used as a countable noun to refer to a specific piece of wood. It is typically discussed in the context of firewood, survival skills, or historical practices.
Examples
