slower

The word 'slower' is a transparent comparative formation built directly on the native English adjective 'slow'. The root 'slow' itself has a deep Germanic heritage, tracing back to the Proto-Germanic slæwaz, which carried connotations of dullness and bluntness, both physical and mental. Over time in English, its meaning expanded from primarily describing a lack of mental sharpness to encompass the more general sense of low speed or long duration. The addition of the comparative suffix '-er', a standard feature in Germanic languages, logically creates a term for a direct comparison of this speed or tempo. Thus, the modern word 'slower' perfectly encapsulates its core logic: the base quality of low speed modified to express a greater degree of that quality relative to something else.

Structure: slow (not fast) + er (comparative suffix) - slow: From Old English 'slāw' meaning "mentally dull, sluggish, torpid." Its origin is Proto-Germanic slæwaz. It functions as the base adjective. - er: From Old English '-ra', the comparative suffix for adjectives, originating from Proto-Germanic -izô. It functions as a grammatical suffix indicating a higher degree of the quality.
