Rhyming Dictionary

Because that's how rhymes get used: a lyric or poem line has a meter, and the rhyme slot has a size — when you need to rhyme 'away' at the end of an eight-beat line, 'stay' (one syllable) and 'yesterday' (three) are different tools for different holes. Grouping by syllables turns the list from alphabet soup into a shelf organized by the thing you're actually shopping for. Multi-syllable rhymes are also the flashier craft — rap in particular prizes two- and three-syllable rhyme chains — so the longer groups are where the impressive options live.

Near-misses that share ending sounds imperfectly — time/mine, home/road, hunger/wonder — matching vowels but not consonants (or vice versa). Three reasons the pros reach for them: perfect rhyme pools are small and deeply mined (love/above has been retired for decades), perfect rhyme in quantity sounds nursery-rhyme-ish, and slant rhyme lets meaning lead instead of forcing the sentence toward whatever rhymes. Listen to any modern chart lyric or read Emily Dickinson: slant is the default, perfect is the emphasis move. When the perfect list here feels stale, the slant section is the craft section.

In perfect-rhyme terms: essentially no — those plus 'month,' 'ninth,' and a few others are the famous rhymeless club, victims of rare ending sounds (obscure proper nouns like Blorenge, a Welsh hill, are the trivia-answer exceptions). But that's precisely what slant rhymes solve: door hinge for orange is the canonical stunt, deliver/quiver work for silver's neighborhood. The practical songwriter move is upstream: if a rhymeless word wants to end your line, rewrite the line so a rhymable word lands there instead — the lyric bends before the dictionary does.

English spelling divorced pronunciation centuries ago — cough, through, dough, and rough share letters and almost nothing else — so spelling-based rhyming would be wrong constantly. The engine uses the CMU Pronouncing Dictionary, which encodes each word's phonemes in General American pronunciation. That accent choice occasionally shows: some pairs that rhyme in British English (or in regional American accents) won't appear, and vice versa. If your own accent rhymes two words, that rhyme is valid in your mouth regardless of the list — the dictionary is a supply depot, not a judge.
