Why fast rhymes the way it does
Fast is built around the flat /æ/ (/æ/); it's one-syllable and spills into a fricative. In our 54,000-word dictionary the perfect-rhyme pool returns 27 matches, family rhymes 1, additive and subtractive together 74, assonance 6,586, and consonance 529. The mix gives you options across the board. Strict rhymes for the structural beats, family or assonance for the interior lines. What matters when you're writing: the ear forgives slants in service of meaning. If the strict rhyme is the predictable word, the assonance match will usually hit harder. Fast is a word where the slant choice almost always reads as more thoughtful than the obvious end-rhyme.
