Etymology

Origin of surge

First recorded in 1480–90; perhaps from Latin surgere “to arise, stand up,” contracted from surrigere, from sur- sur- ² ( def. ) + -rigere, combining form of regere “to make straight, guide, rule”

Explanation

A surge is a sudden strong swelling, like a tsunami wave that engulfs the land. Although a surge offers a fluid image, anything can experience a sudden surge, including emotions, political support, or an angry mob. The original Latin word surgere, meaning “to spring up or rise,” serves as the basis for the word surge, which refers to a great sudden growth or swelling. If you are watching a sad movie and you experience a sudden surge of emotion, do you quietly reach for a tissue, pretend something's in your eye, or simply weep and sob with reckless abandon? Yeah, me too. Christmas shopping can be dangerous when there is a surge of interest in one toy and desperate shoppers surge into stores trying to grab it up.
