- Andornae — A toponymic form in medieval or archaic Latin structurally correlated with old European geographical names or minor historical settlements (often associated in ecclesiastical and historical sources with the hydronymic or toponymic evolution in the Piedmont region or the microstate of Andorra). It represents a structural identity mark preserved almost exclusively in ancient imperial maps, charters, and classical philological works.
- Antiphonary — A liturgical book used in the Christian Church (especially in the Roman Catholic and ancient Byzantine traditions) containing the antiphons, verses, psalms, and hymns designated to be sung alternatively by two choirs throughout the liturgical year.
