Complete couplet: A two-line unit that contains grammatically complete sentences or independent clauses, providing syntactic closure within the couplet form. Complete couplets contrast with enjambed couplets where sentences run across couplet boundaries. This technique creates clear, discrete units of meaning and is characteristic of closed couplets, especially heroic couplets in eighteenth-century poetry. Complete couplets emphasize balance, wit, and epigrammatic concision, making each couplet a finished thought. The form suited neoclassical values of order, clarity, and rational expression, demonstrating how syntactic choices reinforce formal and philosophical commitments.

Complete couplet contains a self-sufficient statement or complete thought within two rhymed lines. Unlike open couplets that run on, complete couplets provide closure and can stand independently, common in heroic couplets.
