Short Answer 
A haiku is a traditional three-line poem with a syllable structure of 5-7-5 that does not rhyme, focusing on rhythm and imagery. It often includes a kigo, or seasonal word, to enrich the poem’s connection to nature, and is typically written in the present tense, reflecting themes of nature, beauty, and personal experiences.
Step 1: Understanding Haiku Structure
A haiku is a unique and traditional form of poetry that consists of exactly three lines. The structure is defined by its syllable count: the first line has 5 syllables, the second line contains 7 syllables, and the third line returns to 5 syllables. Importantly, haiku does not follow a rhyme scheme, making the focus more on the rhythm and imagery.
Step 2: Significance of Kigo
In haiku, it is common to include a kigo, which is a word or phrase that highlights the season associated with the poem. This element adds depth and cultural context that reflects the natural world and the passage of time. Including a kigo connects the reader to the essence of nature, which is essential in traditional haiku writing.
Step 3: Themes and Tense in Haiku
Haiku poems are typically written in the present tense, capturing immediate moments or feelings. The themes often revolve around subjects that resonate with readers, such as nature, beauty, emotions, and everyday experiences. This approach invites readers to engage deeply with the poem and reflect on their own experiences through the lens of a simple yet profound observation.
