Definition of the word twitch

The word "twitch" has its roots in Old English and Middle English. The earliest recorded use of the word "twitch" dates back to the 14th century, where it meant "a sudden quick movement" or "a brief, sharp jerk." This sense of suddenness and quickness remains in modern usage, particularly in phrases like "twitch of the eye" or "twitch of the finger." Over time, the word "twitch" took on a new meaning in the late 17th century, referring to a type of nervous movement or spasm, often occurring involuntarily. This sense is closely linked to the word's Latin root "twitchium," meaning "a sudden or spasmodic movement." In recent years, the term "twitch" has also been adopted as a verb in the context of live streaming and online gaming, referring to the act of suddenly reacting or responding to a situation.
