There are many words that have no rhyme in the English language. “Orange” is only the most famous. Other words that have no rhyme include:
silver, purple, month, ninth, pint, wolf, opus, dangerous, marathon and discombobulate.
But just because these words have no ‘perfect rhyme’ doesn’t mean we can’t rhyme with them. Using slant rhyme, we can rhyme with these words anyway.
