Definition
  1. n. the process of gradually reducing the strength or effectiveness of something through sustained pressure or repeated small-scale losses

Structure

Etymology

Derived from Latin attritio ("a rubbing against"), from atterere ("to wear down"), combining ad- (toward) + terere (to rub). The word originally described physical grinding (e.g., erosion) but evolved metaphorically to denote gradual weakening in contexts like workforce reduction (early 20th c.) and theological repentance (medieval Latin). The core logic persists: steady friction causing incremental loss.
