An “easement” gives someone the right to enter someone else’s property for a specific range of reasons. In legal Latin this is called servitus, because it puts someone else’s property at your service. There are several kinds.
Servitus viae is a right of way.
Servitus itineris is a specific right of ingress or egress, of access into or out of something. You may remember iter (a road, journey or passage) from the opening of Harrius Potter. Iter is a third-declension noun, and itineris is the genitive form.
Ingress and egress, while we’re on the subject, come from the deponent verbs ingredior and egredior.
Officio is to obstruct. If someone propose to erect a tower block in front of your bijou apartment, you may have a case of servitus ne luminibus officiatur: the easement that protects you from having your daylight obstructed, the right “that you not be obstructed with regard to light.”
Servitus tigni immittendi, the right to insert beams into your neighbours walls, won’t arise much in casual conversation. But it is a useful example of the use of the gerundive. Here it is in the genitive, “the right of a beam to be inserted.”
