Listen now (2 mins) | Over time, words with beautiful meanings occasionally get degraded into ugliness. “Gentle,” for example. Originally meaning good natured and kindly, it was twisted into “gentry” in the Middle Ages by very un-gentle land barons seeking a patina of refinement. Then it became a pretentious verb – to “gentrify” – meaning to make something common appear upscale. And now the word has devolved to “gentrification,” describing the greed of developers and speculators who oust middle-and-low-income families from their communities to create trendy enclaves for the rich.
