A more thorough explanation:

Term: Non Decimando
Definition: Non Decimando is a Latin term that means "not to be tithed." It refers to the exemption of certain individuals or groups from paying tithes, which are a type of tax paid to the church. This exemption was often granted to clergy, nobles, and other privileged groups. For example, in medieval England, the clergy were exempt from paying tithes on their personal income and property. This exemption was based on the belief that the clergy were already serving God and the community through their religious duties, and therefore should not be burdened with additional taxes. Similarly, nobles were often exempt from paying tithes on their lands and estates, as they were considered to be providing military and other services to the king in exchange for their privileges. Non Decimando was an important issue in medieval society, as it reflected the complex relationships between church, state, and society.
