An 'outline' is a 2D boundary, while a 'contour' implies a 3D shape or elevation changes. For example, a map's outline shows the country's shape, but contour lines show its terrain.
From Middle English *contour*, from Old French *contour*, from Latin *contornus* ('circular, rounded'), from *contornare* ('to round off'), from *con-* ('together') + *tornus* ('lathe'). The verb sense emerged in the 16th century.
Avoid confusing with 'contour' as a verb in non-technical contexts; it is most natural in art, geography, and makeup. In casual speech, 'outline' is more commonly used.
