In IPA phonetic transcription, the word is written as /ˈdʒʌdər/, where the symbol "dʒ" represents the sound of "j".

Judder is a verb that refers to a sudden, jerky, and unsteady movement or vibration, typically experienced in machines, vehicles, or objects. It is often accompanied by a shaking or trembling motion. The term is commonly used to describe a rapid and irregular oscillation or jolt that causes a repetitive and uncomfortable motion.
Judder can occur in various contexts. For example, when riding in a car, if the brakes are applied abruptly, it can result in a juddering motion as the vehicle comes to a halt. Similarly, when a washing machine is overloaded or unbalanced, it may produce a juddering effect during its spin cycle. In both cases, the irregular motion can produce a sensation of instability, uneasiness, or discomfort.
The term can also be used metaphorically to describe other phenomena. For instance, in cinematography, judder is often used to describe an unpleasant stuttering or flickering effect that occurs when filming fast-moving subjects or when displaying certain types of content on digital screens.
Overall, judder is a concept that encompasses an irregular shaking, trembling, or oscillation, which can be experienced physically or observed visually. It is typically associated with an unsteady and jerky motion that may cause discomfort or perceptual disturbances.
The word "judder" originated in the early 20th century and is believed to be an onomatopoeic formation. It imitates the sound or sensation of something shaking or vibrating unevenly. When a machine or vehicle experiences judder, it produces a jerky or shuddering motion. The exact etymology of the word beyond this is unclear, as it seems to have been coined to describe the phenomenon rather than being derived from existing words or roots.
