A technical or biological term for the rapid closing and opening of the eyelid, often referring to a protective reflex (nictitating membrane) in some animals.
Linguistics
Semantic Notes
Typically used in zoological or medical contexts; in general use, 'blink' or 'wink' are far more common. Can imply a rapid, reflexive action rather than a deliberate wink.
Dialectal Variation
British vs American Usage
Differences
Equally rare in both variants. Slight preference for use in academic/biological texts in both regions.
Connotations
Clinical, precise, archaic-sounding.
Frequency
Extremely low frequency in both corpora. More likely encountered in specialized literature than in speech.

FAQ
Frequently Asked Questions
No, it is very rare and used almost exclusively in formal, scientific, or literary contexts.
'Nictitate' is technical/biological and often implies the action of a specific membrane (the nictitating membrane). 'Blink' is the everyday general term.
Humans blink. The human remnant of the nictitating membrane is the plica semilunaris. We do not have a functional nictitating membrane, so the term 'nictitate' is not typically used for human blinking.
You can, but it will likely sound odd, pretentious, or humorous, as it is an extremely low-frequency word outside specific fields.
