Hay(na)ku is a very simple poetic form, and it's also one of the newest. It was apparently created in 2003 by poet Eileen Tabios.
Hay(na)ku is a 3-line poem with one word in the first line, two words in the second, and three in the third. There are no restrictions beyond this.
A really basic example:
on the playground.
There are already some variations of this new poetic form. For instance, a reverse hay(na)ku has lines of three, two, and one word(s) for lines one, two, and three respectively. Also, multiple hay(na)ku can be chained together to form longer poems.
