The smallest file in WordNet and one of the most vivid: to drizzle, to squall, to thaw. Membership is computed from data the entry already carries, applied to every entry in the corpus, so the list regenerates correctly whenever the corpus changes.
Commonest, longest and average syllables are measured across the 128 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.
