Unlike the perfect rhyme, where both the consonants and vowels at the end of words rhyme completely, the slant rhyme is a type of rhyme where words end in similar, but not identical sounds.
In most cases, words that form the slant rhyme end in identical consonants and different vowels. We can notice this in the given poem as well. Words <em>light </em>and <em>weight</em> end in the same consonant (sound expressed by the combination of letters <em>ght</em>), but different vowels (sounds expressed by letters <em>i</em> and <em>ei</em>). This is why these words create a slant rhyme.
