Slant rhyme occurs when the ending stressed syllables of a word match their consonants but are preceded by different vowel sounds.
The first set of end-rhyme pair that exhibits slant rhyme is:
C. At her low Gate
D. Upon her Mat
In this case, the consonant "t" matches but the vowels are different.
The other set of end-rhyme pair is:
E. Choose One [<em>rhymes with]</em>
F. Like a Stone
The strong and final "n" coincides in both verses but the preceding vowels are different.
This kind of rhyme is also known as<em> imperfect rhyme</em> or <em>near rhyme</em>. Poets use it to provide a variety of rhyming effects and a variation in tone, thus making the poem more interesting for readers.
