^Therefore, since brevity is the soul of wit, ̄ philosophizes the long-winded Polonius in Shakespeare¨s ^Hamlet. ̄ That¨s also a fitting description of 壊艶稼姻霞┗ ! a form of short poetry defined by the Merriam-Webster dictionary as ^a three-line unrhymed Japanese poem structurally similar to haiku, but treating human nature usually in an ironic or satiric vein. ̄

Literally meaning ^river willow, ̄ 壊艶稼姻霞┗ is derived from the pen name of one of its early devotees, poet Karai Hachiemon (1718-1790), who wrote as Karai Senry┗ (凹小寒遭). His collection of 24 booklets, published from 1765 under the joint title Haifuyanagidaru, helped to popularize the genre.

皆艶稼姻霞┗ and haiku share the same economical three-line format, composed of five, seven and five morae, a word sometimes rendered in English as ^syllable, ̄ although that¨s not quite correct. As a general rule of thumb, every unit of sound represents one mora, so therefore two vowels occurring in succession, such as in kau or mae, are treated as two morae. Also, a 陥咄 (sokuon, double consonant), as indicated in both types of kana by the so-called 弌さい仝つ々 (chiisai tsu, small ^tsu^) ! such as in なっとう (稼温岳岳┃, fermented soybeans) or やっぱり (yappari, as I thought) ! is counted as one mora. Finally, a sound ending in ん (n), such as �M (men, noodles) is counted as two morae.
