Etymology
The word 'flatten' is a transparent combination of the adjective 'flat' and the causative verb suffix '-en'. 'Flat' itself has a robust Germanic pedigree, tracing back to Proto-Germanic flata- and further to the Proto-Indo-European root plat-, meaning "to spread" or "broad". This ancient sense of lateral expansion is preserved in the core meaning of 'flat' as a level, even surface without elevations. The suffix '-en' is a productive morpheme in English (as seen in 'widen', 'sharpen') that transforms adjectives into verbs meaning "to make or become [adjective]". Therefore, the literal logic of 'flatten' is "to make flat," a meaning that has extended metaphorically to signify overwhelming defeat or knocking someone down, actions that figuratively reduce an opponent's stature or resistance to a level plane.
