A Cinquain is a poetic form that employs a five-line pattern.
It is usually in the syllabic pattern of two-four-six-eight-two.
This is yet another intriguing, challenging form of poetry like the Diamante or the Nonet.
Here's a Cinquain for a Garden....
Garden
full of blossoms,
bright sight of varied hues,
fragrances wafting in the air
lovely !!
And that's UBC 15 :-)
