Other forms: gentrified; gentrifying
To gentrify is to fix up a neighborhood so that wealthier people want to move there, with the unfortunate result that poor residents can't afford to live there anymore.
This process often begins when middle-class people start buying and sprucing up homes in a poor neighborhood. Over time, more well-off people move in, along with hip coffee shops and fancy restaurants and shops — and house prices and rents go way up. It takes a while to gentrify a whole neighborhood, but eventually it becomes nearly impossible for lower-income people to stay. Gentrify is from gentry, or "nobility," and its root, which means "high-born."
