What does nictation mean?
Nictation is the formal term for blinking, particularly the involuntary or rapid movement of the eyelids. In ordinary use, people simply describe this action as blinking, but nictation is especially useful in medical, biological, and scientific descriptions. It can refer to a single eyelid movement or to repeated blinking, depending on context. Frequent nictation may be associated with irritation, fatigue, dryness, or a neurological condition, although it is also a normal reflex that helps protect and moisten the eyes. The word is therefore more specialized than the everyday expression “blinking” while carrying a similarly neutral meaning. It is most often used when the precise nature or repetition of the eyelid movement is relevant.

Where does nictation come from?
Nictation derives from the Latin nictare, meaning “to wink” or “to blink,” with the English noun formed through the Latin-derived suffix -ation. The verb nictitate and the related Latin nictator come from the same root. The word entered English in the late sixteenth century in the sense “the act of winking.”
