A more thorough explanation:

Term: proditorie
Definition: Treasonably. This word was used in the past to describe actions that were disloyal or traitorous. For example, if someone betrayed their country by giving away important secrets to an enemy, they could be accused of acting proditorie. Another example would be if a person broke a promise to their friends or family in a way that harmed them, that could also be considered proditorie. Essentially, any action that goes against loyalty or trust can be described as proditorie.
