A more thorough explanation:

Morsellum terrae (mor-sel-uhm ter-ee) is a legal term that means "a small parcel of land."

• A farmer may own a morsellum terrae that is used for grazing livestock.
• A developer may purchase a morsellum terrae to build a single-family home.

These examples illustrate how morsellum terrae refers to a small piece of land that can be used for various purposes, such as farming or building a home.
