What does jerkiness mean?
Jerkiness names the quality of movement that is abrupt, uneven, and full of sudden jolts rather than smooth and continuous. It is often used to describe a vehicle, machine, camera, recording, or physical action, as in “the jerkiness of the ride.” The word is usually mildly critical but not automatically severe: a bumpy old road or a low-resolution recording may be described as jerky without implying serious malfunction. In informal social contexts, jerkiness can also mean irritatingly inconsiderate behavior, especially repeated rudeness or an abrasive manner. In this second use, the word is broader and more colloquial than the first, but both senses share an idea of disruption: one describes motion that lacks smoothness, while the other describes conduct that lacks tact.
The quality of moving or operating in abrupt, jerky motions.
"Passengers complained about the jerkiness of the flight."
Common in descriptions of travel, machinery, recorded media, and physical movement; generally critical but often mild.
Irritatingly inconsiderate or abrasive behavior.
"She had little patience for his jerkiness over small disagreements."
An informal and generally disapproving use.
The plural is grammatically possible but rarely needed, since jerkiness is usually used as an uncountable noun.
"The driver noticed several jerkinesses in the machine's movement."
Jerkiness turns a smooth movement into a series of abrupt jolts—and can also describe a person's irritatingly inconsiderate behavior.

Where does jerkiness come from?
Jerkiness is formed from jerk with the suffix -ness, which creates a noun naming a quality or condition. The word jerk developed in English for abrupt or irregular movement, while the modern name for an irritating person emerged later. The precise origin of the older word is uncertain, so its deeper history should not be stated as though it were securely established.
How jerkiness is actually used
The first sense is usually neutral or mildly critical and is common in descriptions of movement, machinery, video, and sound. The second sense is informal and generally means behaving rudely or irritatingly.
