Rhymes depend on the endings of their phonetic pronunciation. The phonetic spellings of the words (buffet, cafe, okay, sleigh) all end the same way, and thus rhyme, even though their normal spellings are different. Homophones have the same phonetic spelling, as in (cinque, sink, sync) or (borough, burro, burrow). Phonetic spellings, part of Mathematica's WordData, use the International Phonetic Alphabet (IPA).
The first list (alphabetic index) sorts words alphabetically. Next to each word is the numeric position of the word in the second list.
The second list (reversed phonetic index) has the word, the phonetic spelling in IPA, and the numeric order. The list was sorted by reversing the phonetic spelling. Words that rhyme will be near each other in this list.
