Etymology: Upheaval is a plain formation: the verb "upheave", meaning to lift or heave up, with the suffix "-al" added to turn it into a noun for the act or result. The "-al" ending itself has a long路径 through Latin, where "-alis" formed adjectives from nouns, passing through Old French and into Middle English before being attached to English verbs. The word's literal sense is therefore physical, a heaving upward, and the modern meaning of sudden social disruption grew out of that image of the ground being forced up and tossed about. The first part, "up", carries the same directional force it has in other English compounds, while "heave" supplies the sense of effort and force. Together they describe something pushed upward by strain, which is why the word works equally well for a geological event and for a sudden break in ordinary social life.
