[edit] Etymology
From Latin erosio (“‘eating away’”), derived from erodere, possibly via erosionem and Middle French erosion.
The first known occurrence in English was in the 1541 translation by Robert Copland of Guy de Chauliac's medical text The Questyonary of Cyrurygens. Copland used erosion to describe how ulcers developed in the mouth. By 1774 'erosion' was used outside medical subjects. Oliver Goldsmith employed the term in the more contemporary geological context, in his book Natural History, with the quote
- "Bounds are thus put to the erosion of the earth by water."
