Describing something that is shaped roughly and not finished smoothly, often giving it a natural or rustic appearance.

Roughhewn → It is formed from "rough" (from Old English "ruh", meaning uneven or coarse) and "hewn" (from Old English "hiwian", meaning to shape or cut). The word "roughhewn" describes something that has been shaped or cut in a coarse or uneven manner.
Think of something that is 'coarse' ('rough') and 'shaped' ('hewn') — that's why roughhewn refers to something that is shaped in a rough manner.
