A more thorough explanation:

concessi

Concessi is a Latin word that means "I have granted." In legal terms, it creates a covenant in a lease for years, but it does not warrant title. It is often used in the phrase "demisi, concessi, et ad firmam tradidi" which means "demised, granted, and let to farm."

When a landlord leases a property to a tenant, they may use the term "concessi" to indicate that they have granted the tenant the right to use the property for a certain period of time. For example, a landlord might say "I have concessi the property to you for one year."

Another example of the use of concessi is in a legal document that outlines the terms of a lease. The document might state "The landlord has granted the tenant the right to use the property for one year, but does not warrant title. This is a concessi covenant."

These examples illustrate how concessi is used in legal documents to indicate that a landlord has granted a tenant the right to use a property for a certain period of time, but does not guarantee that they have clear title to the property.
