It’s the way things go in the modern world. Words and phrases that become popular get overused, and their meaning is stretched to the breaking point. Eventually, the words become meaningless sounds.

“Gaslighting” for instance, came from a 1944 film and used to refer to audacious efforts to deny objectively verifiable reality. Now, people use it to mean anything misleading. “Fan Fiction” once meant amateur-written spin-offs of major published works. Now, it just means “fiction.”
