here's how

the Lakota/Dakota Sioux word
“hau” means “hello”
still is used today
varients are in the native speech
of many plains indians
the Tetons said “howo” or “ho”
Omahas said “hau”

and when the eastern Americans
saw the iridescent colors
shimmering, turning, twisting in the wind
and cascading from trees in the fall
they all said
as we do today
“wow”
