Linguist Geoff Nunberg: “Fifty years after the Summer of Love, that’s been the fate of a lot of the language we associate with that era – faded psychedelia, sort of like acid rock and tie-dye, except that nobody ever tries to revive it. … But it’s striking how many words from the hippie era are still with us, from ‘uptight’ to ‘bummer’ to ‘freak show.’ As brief as the moment was, it changed the way we think and talk.” (includes audio)
