What is the definition of trimeter in poetry?

Trimeter in poetry is defined as having three feet per line. In metrical terms, a "foot" is the basic unit of measurement that consists of a specific arrangement of stressed and unstressed syllables. Since trimeter consists of three of these rhythmic units, it creates a particular flow and musicality in poetry. This meter is often used to create a light or short-paced rhythm, making it common in poetry intended to convey lively themes or emotions. The structure and syllabic count connected to trimeter enable poets to enhance their work's emotional and auditory effects, thus making the correct definition crucial for understanding poetic forms.
