What does scrape mean?

What does scrape mean? Scrape means to rub or drag something across a rough surface so that a thin layer is removed. As a verb, to scrape can be to injure skin by friction, for example to scrape your knee after falling on pavement, or to remove material by scraping, like scraping paint off a wall or scraping ice off a windshield. It can also mean to barely manage, as in to scrape by on a low income, or to collect with effort, as in to scrape together enough money. As a noun, a scrape means a minor wound where top layers of skin are rubbed off, called an abrasion, or a difficult situation, as in to get into a scrape. In medical context, a scrape is a shallow open wound involving epidermis and sometimes superficial dermis, caused by friction, that usually oozes more than it bleeds heavily and stings because nerve endings are exposed. Care involves cleaning gently with water and mild soap, removing debris, applying petroleum jelly, and covering with clean dressing while watching for infection signs.
