A more thorough explanation:

Husgablum is an old English word that means a tax or tribute that people had to pay for living in a house. It was like a rent that people had to pay to the owner of the house.

For example, in medieval times, people had to pay husgablum to their landlords for living in their houses. This tax was usually paid in the form of money or goods.

Another example is that in some countries, people still have to pay husgablum to the government for living in their houses. This tax is used to maintain the infrastructure of the country.

These examples illustrate how husgablum was a tax or tribute that people had to pay for living in a house. It was a way for landlords or governments to collect money from people who lived in their houses.
