Etymology
the word 'roofline' is a modern english compound, transparently formed from two ancient elements. 'roof' descends from the old english 'hrōf', which denoted a covering or ceiling, a term of germanic origin. 'line' traces back to the latin 'linea', meaning a linen thread or a mark, which evolved to signify a contour or boundary. the compound logically combines these concepts to describe the distinctive silhouette or profile created by a roof's structure, a term later extended metaphorically to describe the upper limit or profile of other objects, such as vehicles.
