Ablative rhyme is a rare and specialized term referring to rhymes that function grammatically or semantically as if in the ablative case—implying detachment, source, or means—where the rhyming words evoke a sense of origin, instrumentality, or circumstantial context; though not a standard category in prosody, the concept may be used metaphorically to describe rhymes that subtly reinforce thematic elements of separation or causation, such as rhyming “knife” with “life” to suggest life taken “by” the knife, thereby embedding grammatical nuance within sonic patterning.

Ablative rhyme: A rare or archaic term sometimes used to describe rhymes that "remove" or "strip away" expected sounds, often involving elision or apocope; not standard in modern prosody—verify context if encountered.
