n

Etymology
The word "quake" originates from the Old English verb cwacian, meaning "to shake, tremble, or chatter (as from cold or fear)." This Old English term is part of a family of related Germanic words implying shaking or trembling, such as Middle Dutch quacken and Old Norse kvaka. The core concept is a rapid, involuntary motion, a sense that has persisted from its ancient roots into its modern usage, where it primarily describes the shaking of the earth or a person trembling with strong emotion. Its journey reflects a straightforward evolution from a descriptive verb for physical tremor to a noun naming the phenomenon itself.
Analysis
The word "quake" is a simplex word derived from a single, tight Germanic root. It is not productively formed from smaller, independent morphemes in modern English.
Examples
