Trochaic octameter catalectic is a metrical line of eight trochaic feet (stressed-unstressed) with the final unstressed syllable omitted ("catalectic"), resulting in 15 syllables that end on a strong beat. This uncommon meter produces a pounding, hypnotic rhythm suited to incantation, prophecy, or dramatic monologue. Edgar Allan Poe’s "The Raven" famously uses trochaic octameter catalectic ("Once upon a midnight dreary, while I pondered, weak and weary"), where the truncated final foot enhances the poem’s ominous, relentless cadence. The form’s rarity underscores its specialized expressive power. For students, it exemplifies how catalexis can intensify rhythmic emphasis and emotional gravity, revealing the nuanced relationship between metrical completeness and poetic effect.

Eight trochaic feet with truncated final foot. Even rarer than acatalectic version. See octameter acatalectic for complete version. Challenges both poet and reader's rhythmic stamina.
