What does vellication mean?
Vellication means a slight, involuntary or spasmodic twitching of a muscle, most commonly referring to the eyelid. The term is formal and relatively uncommon, appearing more often in medical descriptions than in ordinary conversation, where people usually say eye twitch, twitching, or spasm. It is especially associated with small, brief movements that are generally harmless, although repeated or persistent muscle twitching can indicate fatigue, stress, irritation, or an underlying neurological condition. The word also has a broader learned sense involving the act of twitching or plucking. Although its precise clinical implications vary with the muscle involved, vellication is useful as a concise term for describing an involuntary contraction rather than a deliberate movement. Its Latin derivation and characteristic final syllables also distinguish it from the more familiar vacation, with which it may be confused in speech.

The plural is used for separate episodes or instances of twitching and is less common than the singular.

Vellication is what your eyelid does when it twitches on its own—an old Latin loanword for a remarkably small involuntary movement.

Etymology of vellication
Vellication entered English in the early 17th century from Latin vellicare, meaning “to twitch” or “to pluck.” The Latin verb was a frequentative form of vellere, “to pull” or “to pluck.” The same root also lies behind English forms such as convulse and evulse, although vellication developed specifically around the idea of a small twitching movement.
