The cinquain, a haiku-like verse-form, was invented in 1915 by Adelaide Crapsey
Here is an example of a semicinquain, a verse form I invented in 2011. The semicinquain is a variant of the didactic cinquain and consists of five lines, the first of which is one syllable, the second two syllables, the third three syllables the fourth four syllables, and the last one syllable again. Unlike the didactic cinquain, there are no rules as to what the syllables can express.
