Etymology

The word "jerk" likely originated in the late 16th century as an onomatopoeic term, imitating the sound or motion of a sharp, sudden movement. Its informal meaning as "a foolish person" emerged in the 1930s, possibly influenced by the erratic behavior associated with jerky motions. The word's simplicity and vivid imagery have kept it stable in English.
