A more thorough explanation:

A CANCELLIS

A cancellis is a term from Law Latin that refers to a chancellor. The term comes from the Latin word "cancelli," which means "lattice." The chancellor was called a cancellis because he performed his duties behind a lattice.

One example of a cancellis is the Chancellor of the Exchequer in the United Kingdom. This person is responsible for managing the country's finances and is considered one of the most important positions in the government.

Another example is the Chancellor of Germany, who is the head of the government and is responsible for making important decisions about the country's policies and laws.

The examples illustrate the definition of a cancellis by showing how the term is used to refer to important government officials who perform their duties behind a lattice or in a private setting. The term is used to describe the role and responsibilities of these officials, as well as their position of authority within the government.
