A form of Japanese poetry. A haiku expresses a single feeling or impression and contains three unrhymed lines of five, seven, and five syllables, respectively.
However there are different forms
Here is one I wrote after watching Rosalie ( our hound ) one snowy winter day in absolute joyful abandon ...snuffling here and there in the garden until she found her sweet spot
I did not observe the 5 7 5 form
wind blows frigid
trees bend and crack
warmth and comfort envelop me
--a bed of berries!
