Final answer:
An estate for years is a type of leasehold estate in real estate that lasts for a specific, fixed duration with definite starting and ending dates.
Step-by-step explanation:
The type of estate that continues for a definite fixed period of time is known as an estate for years. An estate for years is a leasehold interest in real estate for a specific duration. The important characteristic of this estate is that it has a definite start date and a definite end date - no matter how short or long that period may be. Unlike an estate at will or estate from period to period, this does not automatically renew. Moreover, it is different from an estate at sufferance, which occurs when a tenant remains in possession without the consent of the landlord after the lease has expired.
