Here are the features and structure of a Cinquain poem:
1. Line 1: Consists of one word, usually a noun, which serves as the subject or topic of the poem.
2. Line 2: Contains two adjectives or participles that describe attributes or qualities of the subject in line 1.
3. Line 3: Consists of three verbs or verb phrases that express actions or characteristics associated with the subject.
4. Line 4: Contains four words that offer a further insight or observation about the subject. This line often captures the essence or impact of the subject.
5. Line 5: Concludes the poem with one word, which can be a synonym or a related concept to the subject in line 1. This word usually serves as a powerful closing statement or leaves a lasting impression.
The Cinquain poem's structure resembles an inverted pyramid or diamond shape, with the lines increasing and then decreasing in word count. It allows poets to capture and present a concise, evocative, and thought-provoking representation of a topic or idea.
