A cinquain, in poetry, is five unrhymed lines in a 2-4-6-8-2 pattern. Line 1 must be a noun with 2 syllables. Line 2 must be 2 adjectives with a combined 4 syllables, which describe the noun. Line 3 must be 3 -ing words with a combined 6 syllables, which describe the noun. Line 4 must be an 8-syllable phrase or sentence about the noun. Line 5 must be a word (or two) in 2 syllables and must rename the noun. So:
River
Alive, Fertile
Rippling Surging Gasping
Our river gives birth to all life
Mother

Yes! Yes!
Perfect, Profound
Willing, loving, giving
The very best word in the world
Just so
