would you please tell me the differance between these tow words:
(1) blink (2) wink
In American English Blink is the reflex of closing both eyes for a fraction of a second.
Wink is the deliberate act of closing only one eye (as a signal).
In older English wink was used where we now use blink. That's why there are expressions like "Quick as a wink" or "In the wink of an eye" to mean very fast.
