Reconstruction talk:Latin/ando

What is the source of the Italo-Western Romance conjugations of this verb and other Vulgar Latin words? It doesn't seem to be taken from any paper or book so I assume the editor created the table themselves (which is fine), but where could one learn about how these verbs are conjugated? I know that the forms derive rather straightforwardly from those of the Latin, but still. Animatronicity (talk) 08:48, 6 June 2019 (UTC)
