iter

/aytsr/ In the civil law, a way; a right of way belonging as a servitude to an estate in the country (praedium rusticum). The right of way was of three kinds:

(1) iter, a right to walk, or ride on horseback, or in a litter;

(2) actus, a right to drive a beast or vehicle;

(3) via, a full right of way, comprising right to walk or ride, or drive beast or carriage.

Or, as some think, they were distinguished by the width of the objects which could be rightfully carried over the way; e.g., via, 8 feet; actus, 4 feet, etc.

In old English law, a journey, especially a circuit made by a justice in eyre, or itinerant justice, to try causes according to his own mission
