A more thorough explanation:

Definition: Almoin, also known as frankalmoin, is a type of spiritual tenure in which a religious institution holds land with the general duty to pray for the donor. It is a form of free alms, which is a promise to pray for the soul of the donor.

Example: In medieval times, a wealthy landowner might donate land to a monastery or church in exchange for the promise of prayers for their soul. The religious institution would then hold the land in almoin, with the obligation to pray for the donor's soul.

Explanation: This example illustrates the concept of almoin, where land is held by a religious institution with the duty to pray for the donor. The donor gives the land as a form of free alms, and the religious institution accepts it with the understanding that they will pray for the donor's soul. This type of tenure was common in medieval England and was a way for the wealthy to ensure their spiritual well-being after death.
