English wiktionary had over 500k entries as of a few years back. A "word family" is the term for the related forms of a word resulting from derivation, inflection, and other processes. Usually "conjugation" only refers to inflection of verbs whereas "declension" is used for inflection of nouns. And "lexeme" or "headword" are sometimes used to refer to some canonical form of a word family. https://en.wikipedia.org/wiki/Word_family https://en.wikipedia.org/wiki/Word_family https://en.wikipedia.org/wiki/Lexeme https://en.wikipedia.org/wiki/Lexeme
