Oxford Dictionaries has crowned “youthquake” as its word of 2017 in a nod to the unexpected level of youth engagement in this summer’s election in the United Kingdom. An amalgamation of “youth” and “earthquake”, the noun is defined as “a significant cultural, political, or social change arising from the actions or influence of young people”. The word was coined in the 1960s by then-Vogue editor, Diana Vreeland, to describe upheavals in fashion and music caused by Britain’s youth culture.
