Direction

A Path made up of a set of positions in some N-space Domain (by default spatial, or metaphorically, other domains) is determined as a function of a Landmark (which may be incorporated and is usually implicit) and some one-dimensional Independent_variable (time, or, metaphorically, other domains). The Domain and/or the Independent_variable are incorporated in the basic definition of the target. This frame is generally used to describe the motion of something along the Path from the Landmark, which is normally implicitly identified as the location of the viewpoint: We went north . DNI After she was knocked on the head , it seemed like everything had moved three feet to the left . DNI It can often be used for direction of facing and fictive (non-actual) motion as well: Look left and you 'll see it . DNI Words in this frame are commonly used in a fictive motion pattern to identify locations that can be reached by moving in the indicated way from the Landmark: The book was unreachable, 10 feet up on the shelf. DNI East of Mt. Diablo the Sierras rise majestically above the Central Valley. In the second case, the Domain and the Independent_variable are both spatial. They decided to rerate the medication downward in potency . In this case, the Domain is "potency" and the Independent_variable is, as usual, time.
