Eyeblink → It is formed from "eye" (from Old English "ēage", meaning the organ of sight) and "blink" (from Middle English "blinken", meaning to close the eyelids quickly). The word "eyeblink" refers to the quick closing and opening of the eyelids, specifically involving the eye.
Think of the 'eye' as the organ of sight and 'blink' as the action of quickly closing the eyelids. This helps you remember that an eyeblink is the quick action of closing and opening the eye.
