/əˈbreɪʒn//əˈbreɪʒn/

The word "abrasion" has its roots in Latin. The Latin word "abrasio" means "rubbing away" or "wearing away", derived from "ab-" meaning "away" and "rasio" meaning "rubbing". This Latin term was later adopted into Middle English as "abrasion", referring to the process of wearing away or rubbing off of material, often through friction or pressure. In the 14th century, the term began to be used in medical contexts to describe the wearing away of flesh or skin, particularly through friction or rubbing. Over time, the term expanded to include other meanings, such as the wearing away of materials like metal or stone, as well as the process of smoothing or polishing surfaces through friction. Today, the word "abrasion" is used in various fields, including medicine, materials science, and more.
