Etymology

Roots, morphemes, sound changes and borrowings — the history behind words, as a set of records rather than a paragraph of prose.

Reconstructed forms are hypotheses, not attested words. Every entry carries its source; none is invented.

Etymology entries (ETYM-*), cognate sets and semantic-change events attach to a lexeme and a sense. Neither layer exists yet, so building them now would collapse the word/concept distinction the domain specification requires.
