This experimental poetry form is called eighteen words. The form is simple – a poem of eighteen words. There are no other requirements. There are different options for the form such as number of lines, stanza structure, rhyming, meter, etc., however, the only requirement is that the poem has eighteen words.
Here is an example poem:
Dim sum is tasty,
little small things of food,
go have some dim sum.
P.S. Today is a milestone. This is the 450th post on M. Sakran’s blog of and about poetry and poetry related things.
