What does nictate mean?
Nictate means to blink or wink, particularly in a rapid, repeated, or involuntary manner. The word is most often used in technical and descriptive contexts involving eyes, eyelids, or animals. Birds, reptiles, and other animals may nictate to moisten their eyes, protect them from bright light, or remove debris. A nictitating membrane, familiar in birds as the transparent third eyelid, moves rapidly across the eye for similar purposes. Although nictate is precise and evocative, ordinary speakers would usually choose 'blink' in everyday conversation. It can also describe involuntary eyelid fluttering caused by fatigue, irritation, or exposure to light. In literary or formal writing, nictate adds a vivid impression of quick, rhythmic movement and can suggest both biological function and expressive character.

The blinking you do unconsciously to keep your eyes moist is called nictitation, and a bird's third eyelid is famous for doing the same job.
