pockmark

The word 'pockmark' is a transparent compound from two deeply rooted Germanic elements. 'Pock' originates from the Old English term for a pustule or blister, a word common across Germanic languages describing the physical manifestation of diseases like smallpox. 'Mark' derives from the Old English word for a boundary or sign, evolving to mean any visible impression or trace. When combined, the term literally means "the sign left by a pustule," directly linking the cause (the pock) to its lasting effect (the mark). This logical compounding created a precise term for the distinctive scarring, which later extended metaphorically to describe similar pits or indentations on inanimate surfaces.

Structure: pock (disease mark) + mark (sign) - pock: From Old English 'poc' (a pustule, blister), via Proto-Germanic puk-, referring to a swelling or protuberance. Its functional role is the core semantic root, specifying the type of lesion. - mark: From Old English 'mearc' (boundary, sign), via Proto-Germanic markō. Its functional role is the general noun, specifying the visible sign or trace left behind.
