Well, now......here's something I never knew before, and now that
I know it, I feel compelled to send it on to my more intelligent
friends in the hope that they, too, will feel edified. Isn't history
more fun when you know something about it?
Before the Battle of Agincourt in 1415, the French, anticipating
victory over the English, proposed to cut off the middle finger of
all captured English soldiers. Without the middle finger it would be
impossible to draw the renowned English longbow and therefore they
would be incapable of fighting in the future. This famous English
longbow was made of the native English Yew tree, and the act of
drawing the longbow was known as "plucking the yew" (or "pluck
yew").
Much to the bewilderment of the French, the English won a major
upset and began mocking the French by waving their middle fingers at
the defeated French, saying, See, we can still pluck yew! Since
'pluck yew' is rather difficult to say, the difficult consonant
cluster at the beginning has gradually changed to a labiodentals
fricative F', and thus the words often used in conjunction with the
one-finger-salute!
It is also because of the pheasant feathers on the arrows used
with the longbow that the symbolic gesture is known as "giving the
bird."
And yew thought yew knew every plucking thing
