What does twitch mean?
Twitch refers to a quick, abrupt movement or to the action of making such a movement. The word is especially associated with an involuntary muscular contraction, as in a nervous eye twitch or a twitching leg, but it can also describe pulling or jerking something sharply. A twitch is generally briefer and less rhythmically repetitive than a spasm or a tic. Figuratively, the noun denotes a slight, sudden emotional reaction: a person may show “a twitch of guilt,” “a twitch of anxiety,” or “a twitch of recognition.” The verb is similarly flexible and often implies that a person is struggling to control a reaction, although controlled or deliberately made twitches are also possible. Its long history and compact sound make it especially useful when describing small but conspicuous gestures, whether physical or emotional.
To move suddenly and sharply, especially as an involuntary muscle contraction; also, to pull or jerk something quickly.

Where does twitch come from?
Twitch comes through Middle English twichen from Old English twiccan, meaning “to pull” or “to pluck.” It is connected with related Germanic forms, including Dutch twitschen, German zwicken, and Old Norse twiska. The modern sense of making a sudden or spasmodically movement developed from the older meaning of pulling sharply.
