Origin:

The word "throttle" originally referred to a small lump or swelling in the throat, from the Old English word "throte" (throat) and "bolla" (rounded object). Over time, the term came to be used for any device that controlled the flow of a fluid, as it resembled a small lump or ball in the flow path.

The first known use of the word "throttle" in the context of controlling a fluid flow was in the 16th century, when it was used to describe a device for regulating the air supply to an organ. In the 19th century, the term was adopted for use in steam engines and other machines that required precise control of fluid flow.

Today, the word "throttle" is commonly used in engineering, automotive, and aviation to refer to a device that controls the flow or motion of a fluid or energy source. It is a critical component in many industries, ensuring efficient and reliable operation of engines, pumps, and other systems.
