Numeric rhyme is a poetic technique where rhyme is determined not by phonetic similarity but by numerical equivalence—such as matching line numbers, syllable counts, or positions within a sequence—to create structural echoes rather than sonic ones; this experimental approach, often associated with conceptual or constraint-based poetry, subverts traditional expectations of auditory harmony in favor of abstract patterning, as in poems where the first and tenth lines “rhyme” because they occupy mirrored positions, or where stanzas correspond numerically to dates, ages, or other quantifiable data to embed hidden meaning.

Numeric rhyme links lines by syllable count rather than sound (e.g., 8-syllable lines rhyming). Rare; often experimental. Contrast with sight rhyme. Useful in constrained writing—check if numeric patterns support thematic structure.
