Slant rhyme pairs words that sound close but do not fully rhyme. The match may come from similar vowel sounds, similar consonant sounds, or both, but the ending is not exact. Poets use slant rhyme to create a subtle link between lines without the stronger, more obvious effect of perfect rhyme.
Example
The moon hung low above the street,
while cedar shadows brushed the fleet
of thoughts that drifted, thin and bare,
between the lamp and cooling air.
