To make rough or rougher; to roughen a surface.
From Latin 'asperare', derived from 'asper' meaning rough. The suffix '-ate' is a common verb-forming ending in English, inherited through Romance languages from Latin verb conjugations.
This word is rarely used in modern English, but it captures an important action in manufacturing and surface treatment—deliberately making something rough can improve grip, adhesion, or aesthetic texture, which is why sandblasting and wire-brushing are still essential industrial techniques.
