Typically, judders cause an object or surface to shake or tremble in an irregular and unsettling manner, often producing a stuttering or jarring effect.
The term is commonly used to describe mechanical or electronic devices that display a shaky or unsteady behavior. For instance, a malfunctioning washing machine or a vehicle with a faulty engine may experience judders, leading to a noticeable trembling or vibrating sensation. Similarly, in cinematography, judders can occur when there is a lack of smoothness in the camera movement, resulting in an uneven sequence or visual disturbance.
Judders can also describe a physical sensation experienced by individuals. For example, it can refer to the sudden quivering or shivering of a person's muscles or limbs, which may occur due to medical conditions such as Parkinson's disease or as a reaction to extreme cold temperatures.
Overall, judders encompass a range of rapid, irregular movements and vibrations that are often disruptive or uncomfortable to observe or experience.
The word "judders" is originally derived from the verb "judder". The etymology of "judder" can be traced back to the late 19th century, originating as an onomatopoeic word. It was coined to imitate the sound or sensation of a vibrating or tremulous movement. The word "judder" later gave rise to the noun "judders", which refers to the repeated shaking or trembling motion, often used to describe a vehicle or machinery that is vibrating excessively.
