abrasive
uh-BRAY-siv
/əˈbreɪ.sɪv/
A substance or material used for grinding, polishing, or cleaning a hard surface by rubbing; harsh or rough in manner.
In physical contexts, it refers to sandpaper or grit. In social contexts, it describes a harsh, grating, or unpleasant personality.
The story behind the word. Abrasive comes from the Latin 'abradere', meaning 'to scrape off'. This is composed of 'ab-' (off, away) and 'radere' (to scrape), which is also the ancestor of words like 'razor' and 'erase'.

- rough: Rough is a general description of a surface, while abrasive implies the active capability to wear down or scratch another surface.
- harsh: Harsh describes severe conditions or attitudes, whereas abrasive specifically implies a grating friction in physical or social interactions.
- gentle: Gentle implies soft, smooth, and non-damaging, the opposite of abrasive.
- lubricant: A lubricant reduces friction, whereas an abrasive relies on friction to wear down surfaces.
