Hoodwink
Etymology
Literally "to blindfold." In the 1500s "wink" meant to close the eyes, and to "hoodwink" was to cover someone’s eyes with a hood — a real practice in games and in falconry. From physically blinding someone the meaning moved to figuratively blinding them: keeping them from seeing the truth. The deception sense had taken over by the 1600s.

What it names
