Words outlive people, institutions, civilizations. Words spur images, associations, memories, inspirations and synapse pulsations. Words send off physical resonations of thought into the nethersphere. Words hurt, soothe, inspire, demean, demand, incite, pacify, teach, romance, pervert, unite, divide. Words be powerful.
Grown-ups and children are not readily encouraged to unearth the power of words. Adults are repeatedly assured a picture is worth a thousand of them, while the playground response to almost any verbal taunt is 'Sticks and stones may break my bones, but words will never hurt me.' I don't beg so much as command to differ.
