The length of time that an agreement, such as a tenancy agreement, is meant to last. For example, a lease that goes from April 1 to the following March 31 has a term of one year. This is also called a fixed term tenancy. During this time, neither the landlord nor the tenant can end the tenancy unless the other one does something that seriously breaks the agreement.
When the term is over, it does not mean the tenancy ends. The tenancy automatically turns into a periodic tenancy unless the landlord or tenant does something to end it.
Term can also mean a detail or part of the agreement, for example, that the tenant will not hang things from their balcony railing, or that the landlord will provide parking for visitors.
