n. A technique for creating the appearance that the object of a drawing is extending into space by shortening the lines with which that object is drawn.

v. Present participle of foreshorten.

n. Representation in a foreshortened mode or way.

n. In perspective, the representation of figures pointing more or less directly toward the spectator standing in front of the picture, or away from a plane perpendicular to the spectator's line of sight, but shown in such a manner as to convey to the mind the impression of their just length.

"This becomes complicated and more difficult to arrange when we admit into our design anything resembling what painters call foreshortening, and the awkwardness is felt even in the placing of such a small thing as an apple-leaf, which may be treated in such a way that the intention of the drawing is entirely lost in the confusion which arises between the inferred and the actual projection."
