Plowed out or scraped away; having grooves or furrows engraved on the surface.
From Latin 'exaratus', past participle of 'exarare' (to plow out), from 'ex-' (out) + 'arare' (to plow); originally a farming term that became used in botany and zoology.
This word perfectly captures what happens when something gets deeply carved or furrowed—like when water erodes grooves into rock or when a beetle leaves tracks that look like they've been plowed into bark.
