1. Syllable Structure: It must follow a strict syllable count:
* 5 syllables in the first line
* 7 syllables in the second line
* 5 syllables in the third line
2. Focus on Nature: Haiku traditionally explore nature and its beauty. This doesn't mean it *has* to be about nature, but it often is.
3. "Kireji" (Cutting Word): A haiku often contains a "kireji," a word or phrase that creates a sudden break or shift in the poem. This adds a sense of surprise or contemplation.
Here's an example:
*Falling leaves dance down*
*Golden hues paint the air,*
*Autumn's quiet touch.*
This haiku follows the syllable structure, focuses on nature (falling leaves, autumn), and uses "quiet touch" as a kireji to create a sense of peace.
