Usage: Use "blink" as a verb when describing the reflexive action of briefly closing one's own eye to clear it, rather than using it for intentional winking at someone else. As a noun, refer specifically to that single instance or rapid movement itself.
The word "blink" comes from Old English blincan, which originally meant to gleam or shine before shifting in Middle English to describe the rapid closing and opening of an eye. It is related to other Germanic words that also refer to flashing light or shining brightly.
