Trimeter line is a metrical line consisting of three feet, commonly used in English poetry for its brisk, lyrical, or ballad-like rhythm. Depending on the foot type, trimeter can be iambic (da-DUM da-DUM da-DUM), trochaic (DUM-da DUM-da DUM-da), anapestic, or dactylic, each imparting distinct emotional and narrative effects. Iambic trimeter appears in hymns and light verse; trochaic trimeter in Blake’s "The Tyger"; anapestic in limericks. Its brevity lends itself to epigrammatic statements, song refrains, or rapid narrative pacing. For students, mastering trimeter reveals how line length shapes poetic tempo and tone, offering a versatile tool for balancing concision with musicality in both traditional and experimental contexts.

Verse line containing three metrical feet. Common in hymns, ballads, nursery rhymes. Often paired with tetrameter. Study examples in iambic and trochaic meters for versatility.
