Recently I read that Tankas are a form of Haiku that add two lines of seven syllables each. This format may have preceded the Haiku form. Both challenge the writer and perhaps the reader to consider how effective language can be when not overused. I wish my work allowed me to use Haiku as a format, but as an avocation it is an enjoyable pursuit.
Winter winds wander through it
Turning and churning
Thoughts are whirligigs as well
Spinning thoughts can bear good fruit
