Jerkiness → It is formed from "jerk" (originating from the late 19th century, possibly from the verb 'jerk', meaning to pull or move suddenly) and the suffix "-iness" (meaning the quality of being). The word "jerkiness" refers to the quality of being jerky or having sudden, sharp movements.
Think of the sudden movements of 'jerk' and remember that 'jerkiness' describes the quality of those sharp, abrupt motions.
