auctoris-

Morpho's Latin capability is in its infancy. Many of the entries in the wordwheel may not have parse information or link to a incorrect or nonexistent lemma in Logeion. If you would like a second opinion on our parse, we recommend our local install of Whitaker's Words. You can also consult LemLat (this will take a moment).

Alas! Could not find the search term auctoris-.
