The word is a modern compound adjective formed within English by combining the comparative form of 'high' with the noun 'resolution'. 'High' originates from a robust Proto-Germanic root meaning tall or elevated, which evolved into a broad metaphor for degree or intensity. 'Resolution' has a more technical journey, stemming from the Latin concept of "loosening" or "breaking into parts," which in optics and imaging came to signify the ability to distinguish or separate fine details. Therefore, 'higher-resolution' literally means "of a greater degree of detail-separation," directly linking the comparative concept of 'more' with the technical capacity for fine visual or analytical clarity.

Structure: high (elevated) + er (comparative suffix) + resolution (clarity) high: From Old English hēah, meaning "tall, lofty, high." It functions as the base adjective describing a great vertical extent or degree. er: A comparative suffix from Old English -ra, used to form the comparative degree of adjectives and adverbs. resolution: From Latin resolutionem (a loosening, releasing), itself from re- (again) + solvere (to loosen). In this compound, it functions as a noun meaning the degree of detail or clarity discernible.
