A more thorough explanation:

Feodi firma, also known as fee farm, is a type of land tenure where the land is held in perpetuity at a yearly rent, without any additional services required besides those stated in the original agreement. This means that the landowner pays a fixed rent to the landlord, and in return, they have the right to use the land as they see fit.

For example, a farmer may hold land in feodi firma, paying a yearly rent to the landlord. In return, the farmer has the right to use the land for farming without any additional obligations.

The term feodi firma has its roots in Old English and Norman French, and it has been used throughout history to describe various forms of land tenure. However, the basic concept remains the same: the land is held in perpetuity at a fixed rent, without any additional obligations.
