The list began my junior year in high school. My best (and often only) friend Mary and I somehow or other began a list of what we considered groovy words, "groovy" itself being one of them in those mid-1960s days.
Many were of pre-Columbian Mesoamerican origin -- Teotihuacan, Tenochtitlan, Macchu Picchu -- because Mary and I were in Spanish class together and our teacher, Charles Schlereth, was introducing us to the native cultures of Mexico and Central and South America.
There were also a lot of French words on the list -- fait accompli is the first that springs to mind without actually looking at the original compilation, and gendarme -- as well as just interesting words that we came across in our reading, such as juggernaut and klipspringer and rambunctious.
I kept track of my copy of the list in a spiral notebook; Mary kept hers, too, though I'm not sure where. Forty odd years later, at a class reunion in 2006, we met again for the first time in decades and both of us had the lists with us.
Words meant a lot to us then, and still do.
