Near rhyme uses words or sounds that echo each other without matching exactly. The effect is less complete than perfect rhyme, but the repeated vowel or consonant sounds still create a sense of connection, tension, or subtle musicality. It is often called slant rhyme or half-rhyme, though poets may also achieve it through assonance or consonance.
Example
The lake held dusk in a silver shiver,
while the pale reeds whispered and quivered.
