A more thorough explanation:

Definition: Venditor (ven-də-tər) is a historical term that means a seller, usually of real property. It is also known as a vendor.

Examples:

• John was the venditor of the house that Mary bought.
• The itinerant vendor traveled from town to town selling his wares.

The first example shows how the term venditor can be used to refer to someone who sells real property, in this case, a house. The second example illustrates the term itinerant vendor, which refers to a seller who travels from place to place selling goods.
