A more thorough explanation:

Definition: Lignagium is a historical term that refers to the right to cut firewood and the payment for that right.

• A farmer was granted lignagium to cut firewood from the forest on his property.
• The lord of the manor charged his tenants lignagium for the right to gather firewood from the common land.

These examples show how lignagium was a legal right to cut firewood and the payment made for that right. It was often granted by landowners to their tenants or farmers who needed firewood for heating and cooking.
