abrade ə-ˈbrād verb
1. rub hard or scrub
2. wear away
The word abrade has appeared in four articles on NYTimes.com in the past year, including on April 25 in “An Amputee’s Toughest Challenge Yet: Her 140-Mile Run in the Desert” by Jeré Longman:
On the bottom of her running blade in the Sahara, Palmiero-Winters wore a scrap of Goodyear tire, three and a half inches wide, for traction. The prosthesis included an air chamber to cool its outer and inner layers. Then the leg was coated in a chalky color with paint used on the roofs of houses and buildings in the desert.
It was critical to keep sand from getting between Palmiero-Winters’s skin and the silicon liner of her prosthesis, said Schaffer, who fashioned the prosthetic leg. The rubbing would mercilessly abrade her skin, he said, not unlike trying to run a marathon in a bathing suit full of sand.
