Ambiguity is kept

Every structurally valid lemma-analysis pair is shown. Nothing is silently collapsed to a single preferred parse.

Ordering is not judgment

Candidates are ordered by Collatinus lemma frequency from the LASLA corpus — classical counts, not Ecclesiastical or Vulgate measurements.

Spelling is normalized

æ → ae, œ → oe, j → i, v → u, and vowel-quantity marks are stripped before lookup. The form you typed is preserved above.

Where this comes from

Built by the Lingua Sacra Institute.

This dictionary runs on the same morphological analyzer that powers the Lingua Sacra Reader. The Institute's other Latin learning resources live at linguasacra.org All of them free, or as low-cost as we can make them.
