Homoeoteleuton (also spelled homoioteleuton) is a rhetorical device involving the repetition of similar endings in successive words or clauses—such as "-tion" or "-ing"—to create rhythmic cohesion and sonic texture; common in biblical parallelism and Latinate diction, it appears in poetry like Milton’s “Of Man’s first disobedience, and the fruit / Of that forbidden tree,” where terminal similarity enhances cadence and mnemonic force without strict rhyme.

Homoeoteleuton is similarity of endings in nearby words or lines, sometimes a rhetorical device but also can refer to copying errors when lines end alike.
