Words whose spelling carries a letter the pronunciation does not — identified by comparing letter count with syllable structure across the commonest silent patterns. Membership is decided by a property of the word you can check yourself — its letters, its syllables or where its stress falls — applied to every entry in the corpus.
Commonest, longest and average syllables are measured across the 333 words carried on this page, ordered by how often each appears in everyday English.
Definitions, subject classification and semantic relations come from WordNet. Syllable counts come from the CMU Pronouncing Dictionary where the word is recorded in it. Full sources and licences.
