Outline is, literally, the outer or exterior line; but the word is freely used for a representation by the principal or distinguishing lines. Contour and profile retain this distinctive meaning of the outside line, the former referring to the boundary of the whole figure in any position, and the latter to the boundary of face or figure when seen directly from one side, with figurative uses in architecture and surveying. A sketch fills up the outline to a greater or less degree, not completely, but so that a lively idea of the original object or scene is conveyed. Delineation is rather indefinite, but is more than an outline and may be complete. Outline, sketch, and delineation bear the same relation to one another when used to express the representation of a subject in words.To draw the exterior line of; draw in outline; delineate; sketch the main features of.
