The quality of being rough or harsh, often causing wear or irritation.
The abrasiveness of the sandpaper made it effective for smoothing surfaces.
Abrasiveness → It is formed from "ab-" (meaning away) and "radere" (meaning to scrape). The word describes the quality of being able to scrape away or wear down surfaces.
Think of something that scrapes 'away' ('ab-') — that's why abrasiveness refers to the quality of being rough or capable of wearing down.
