What does detrition mean?
Detrition is the gradual process by which a material is worn away through friction. It may result from the rubbing of rock against rock, the abrasive action of particles, or the repeated contact of mechanical components. In geology, the term describes the erosion that gradually reduces exposed surfaces and helps produce loose material known as detritus. Detriction is similar to erosion and abrasion, but it places particular emphasis on the mechanical effects of rubbing and friction. The word is formal and technical rather than conversational, and it is encountered especially in geology, engineering, and the study of materials. Although the term can describe rapid wear under severe conditions, it often conveys a slow, cumulative process. It is also useful in figurative descriptions of gradual loss or damage, provided the underlying image of something being worn away remains clear.
nounThe gradual wearing away or erosion of a material through friction. The term is used chiefly in geology, materials science, and related technical contexts.
- The gradual wearing away or erosion of a material through friction.
"Years of wind and water caused the gradual detrition of the exposed cliff face."
"The gradual detrition of the cliff face created a narrow shelf of sand below."
"Abrasive particles rapidly increased the detrition of the machine's cutting edge."
The plural is grammatically regular but uncommon; the singular is normally preferred.
"Repeated detritions progressively rounded the exposed stone."
Detrition is the action; detritus is the debris left behind.

Where does detrition come from?
Detrition comes from Latin detritio, meaning a wearing down, which was derived from deterere, to wear down or rub away. The English word dates from the early 17th century. Its relatives include detritus, denoting fragmented material produced by erosion, and detritivore, an organism that feeds on such material; both ultimately trace to the same Latin tradition of rubbing or wearing.
How detrition is actually used
A formal and chiefly technical term. It is especially common in geology and materials science, while general usage tends to prefer erosion, abrasion, or wear.
Easily confused with detrition
Detrition is the process of wearing material away, whereas detritus is the loose material or debris produced by erosion.
