Etymology
the word "earthquake" is a transparent compound formed from two old english roots. "earth," from the proto-germanic erþō, refers to the ground or soil, while "quake," from the proto-germanic kwakōną, means to shake or tremble. the compound literally means "a shaking of the ground," a meaning that has remained remarkably consistent from its old english formation to modern usage. it exemplifies the germanic tendency to create descriptive, literal compounds for natural phenomena, where the combined sense of the parts directly and logically conveys the whole concept.
Analysis
