I've heard about it recently. It's a Japanese form of poetry. Having lunch at my desk today, I browsed Haiku on the internet and found samples and a set of rules tied to it, and believe me, they are intimidating, especially for someone who never studied poetry or writing. This is what I learned while having my very exciting cottage cheese lunch.
Haiku poems consist of three lines (or units), each having a number of syllables - 5 syllables, over 7 syllables, over 5 syllables. Total: 17 syllables. That's not enough! The poem must include a kigo, a word connecting to or relating to a season, i.e. "snowy" as in Winter. Each unit must also compliment the others and there are other rules I just flat out ignored. There are many definitions of Haiku poems for different languages and this is the one I tripped over.
A photo I previously posted came into mind and I thought about it. Then, I reached for a piece of paper and pen and scratched away. By the time I finished my delicious lunch, I rewrote what I came up with and slipped it into my handbag.
Here is my feeble attempt at Haiku. I'm one syllable short. Oh, well. I'll give it another try one day.
Chill descends deeply
Koi succumb to the nature
Drenched in slumber.
